AB  - Bacterial and fungal resistance is an increasingly severe problem. The high microbial resistance appears to be the consequence of the unconsidered use of antibiotics and antifungal drugs, and poor infection control in hospitals. Fighting microbial resistance by using new substances based on organic nanoparticles, carbon dots (CDs) may be a promising strategy in developing new therapeutic approaches. The metal-organic frameworks (MOFs), due to their unique features including high cargo loading, biodegradability, and ability of modification have become an attractive group of nanomaterials used in several fields including nanomedicine. In the current study, we synthesized N- and S-CDs@AgMOFs nanocomposites, new substances based on organic CDs nanoparticles inserted in MOFs structures. One Gram-positive (Bacillus subtilis), one Gram-negative (Escherichia coli) bacteria, and one fungi (Candida albicans) were treated with different concentrations (15.625, 31.25, 62.5, 125, 250, 500, 1000, and 2000 mg/L) of N- and S-CDs@AgMOFs nanocomposites during 48 h. The results showed the bactericidal effect of N- and S-CDs@AgMOFs on Bacillus subtillis and the antifungal effect on Candida albicans. The effect of S-CDs@AgMOFs was stronger on bacterial cells compared to the N-CDs@AgMOFs, while both agents affected fungi in equal concentrations, indicating different mechanisms in the two types of microorganisms. In Candida albicans, minimal inhibitory concentration (MIK) of both nanocomposites was 125 mg/L, while in Bacillus subtilis MIK of N-CDs@AgMOFs was 500 mg/L and for S-CDs@AgMOFs was 250 mg/L. It can be concluded that tested nanocomposites are safe for the environment because they are not toxic in the concentrations in which they can be found in the environment.

AB  - The various applications of cerium oxide nanoparticles (nCeO2), one of the most produced metal oxide nanoparticles, could affect environmental health due to accumulation of uncoated and coated nCeO2 with increased suspension stability. The trans-generational effects on seed characteristics are important components of the life histories of plants representing the pathway from adult to offspring that completes the life cycle. The effects of carbohydrate-coated nCeO2 on the plant seeds through the generations are still unknown. The main aim of this study was to investigate the effect of the treatment of maternal Sinapis alba and Chenopodium rubrum plants with 200 mg/L of uncoated (CeO2) and glucose-, levan-, or pullulan coated nCeO2 (G-, L-, оr P-CeO2) on germination of three generations of seeds. Sinapis alba was selected as a hyperaccumulator of heavy metals, while Chenopodium rubrum was selected as a short-day plant and weed. In Sinapis alba, the results of germination on the 4th day revealed increased germination after the treatment with CeO2 and L-CeO2 nanoparticles in zero generation and after all nCeO2 treatments in the 1st and 2nd generation of seeds. In Chenopodium rubrum, there were no changes after the treatments. It can be concluded that trans-generational effects of the different nCeO2 treatments persist to at least the second generation in seeds. Compared to the same generation control, the 2nd generation of seeds showed the highest sensitivity. The coated nCeO2 were more effective than the uncoated ones. Enhanced germination in three generations of S. alba seeds recommends nCeO2 for application in seed-priming.

AB  - Manganese (Mn) is an essential element for plant growth. For metabolic function, Mn2+ is required at low concentrations, but Mn2+ excess can change the activity of various enzymes and interfere with the absorption and translocation of some minerals such as Ca, Mg, Fe, and P. Mn availability to the plants depends on pH of the growth medium and on root exudates for Mn chelation or reduction. The main aim of this research was to investigate the effect of Mn2+ on the main parameters of secondary metabolism: total phenolic content (TPC) and total antioxidative activity (TAA) in maize (Zea mays L.) shoots and roots. Maize was chosen as agricultural species important for human and animal nutrition, and a simply cultivated plant. Maize seeds (inbred line Va35) were germinated in distilled water and then transferred into the hydroponic (KNOP/2) growth solution. Mn2+ was applied in two different concentrations (5 and 100 μM) by adding MnSO4 into the hydroponic solution. After 7 days (December 2021) of growing under 8/16h photoperiod, the leaves and roots were collected. The TPC was measured according to Folin-Ciocalteu’s spectrophotometric procedure, while TAA was determined by ABTS/HRP assay. The results showed that TAA was significantly decreased only in maize roots after the treatment with 5 μM Mn2+, while higher Mn2+ concentration (100 μM) did not change TAA in maize roots. TAA in shoots and TPC in both parts of maize was unchanged. Finding that 5 μM of Mn2+ have decreasing effect on maize antioxidative activity without harming plants indicates that lower concentration can be more toxic due to: 1. plants excreting an excess of Mn2+ into the environment after the treatment with high Mn2+ concentration and 2. Mn can affect the metabolism of small molecules (enzymes or phytochelatins) binding for them and decreasing the total ROS scavenging activity.

AB  - Cerium oxide nanoparticles (nCeO2) are attracting continuously growing attention due to their unique properties  - their facile transition between Ce3+ and Ce4+ oxidation states. nCeO2 found application in the industry, cosmetics, agriculture, electronics, etc.  Their final accumulation in the environment creates new environmental stress factors for living organisms. To improve their solubility, nCeO2 were coated with monosaccharide - glucose and microbial exopolysaccharides - levan and pullulan to obtain glucose-, levan-, and pullulan-coated nCeO2 (G-CeO2, L-CeO2, and P-CeO2). The potential long-term effect of nCeO2 on vegetation was studied in two herbaceous weedy annuals - Sinapis alba and Chenopodium rubrum. It was suggested earlier that the mechanism of maternal environmental effects, that persists for several generations, can act through relative seed protein composition representing an “archive“ of environmental changes experienced by mother plants during their lives. Treatment with nCeO2 of Sinapis alba and Chenopodium rubrum seeds during germination, on total protein content (TPC) and protein profile of seeds produced in two subsequent offspring generations grown in the greenhouse, were investigated. The TPC mainly showed no significant differences, both between treatments and between subsequent generations, in both species. SDS-PAGE electrophoresis showed the presence of 15 protein bands, molecular weight 10 - 140 kDa, in all seed samples of Sinapis alba or Chenopodium rubrum, respectively. We showed that nCeO2 treatment during the very early development of mother plants (germination) has a long-term effect, visible in the difference in width and intensity of seed protein bands of seeds sampled in two subsequent offspring generations.

AB  - Cerium oxide nanoparticles (nCeO2) are nanomaterial widely used in electronics, cosmetics, catalysis, and fuel additives production due to their transition between Ce3+ and Ce4+ oxidation states. Their increasing production (around 10,000 metric tons per year) makes them one of the most produced metal oxide nanoparticles which can lead to unexpected consequences to environmental health and safety. Coating nCeO2 with different polymers is a very popular way to increase their suspension stability, but the data on their effect on cultivated plants are scarce. Environmental effects on morphological and physiological properties of offspring which occur during the development of the mother plant are called maternal environmental effects. Their expression depends on the offspring’s environment, they are expressed throughout the life cycle of the offspring and may persist for several generations. It was suggested that components of the nonenzymatic antioxidant system might participate in the mechanism governing the maternal environmental effects. Total antioxidant activity (TAA) comprises the contribution of different non-enzymatic components with antioxidant capacity. Herbaceous weedy annuals Sinapis alba and Chenopodium rubrum were selected, as a heavy metal hyperaccumulator plant i.e. a species with strong maternal effects, respectively. The effect of uncoated (CeO2) and glucose-, levan-, and pullulan- coated nanoparticles (G-CeO2, L-CeO2, P-CeO2) treatment of Chenopodium rubrum and Sinapis alba seeds during germination, on TAA of seeds produced in two subsequent generations of plants grown in a greenhouse, were investigated. TAA was measured using the ABTS/HRP end point method. Results showed that the effect of nCeO2 treatments was more expressed in Sinapis alba seeds; mainly all nanoparticles treatments during germination of mother plants resulted in the increase in TAA of produced seeds in both monitored generations. In contrast, in Chenopodium rubrum CeO2 treatment resulted mainly in the decrease in TAA of produced seeds in both monitored generations. The presented effect was equally expressed in both generations. Among nanoparticles, L-CeO2 showed the most pronounced effect in both generations of the plants. We showed that the effect of nCeO2, applied during the early development of mother plants (germination), is visible in changes in the components of the nonenzymatic antioxidant system of produced seeds and that it persists for (at least) two generations. In other words, seed priming with nCeO2 might affect changes in yield antioxidant capacity through several generations.

AB  - Copper (Cu) is an essential microelement in various processes in the cell wall, such as wall synthesis and loosening, but Cu excess due to human activities increase soil pollution and can induce harmful effects. Alleviation of Cu toxicity could be ameliorated in various ways such as adding organic compounds and cations (Ca2+, Mg2+). This study aimed to reduce Cu toxic effects using organic nanoparticles as potential nano-fertilizers obtained from folic acid. Carbon dots (CDs) are biocompatible and non-toxic nanoparticles with chemical affinity to some heavy metals. In this research, CDs were applied in two different concentrations - 167 mg/L and 500 mg/L with or without 5 µM Cu2+ during the growth of maize plants in hydroponic solution. Cu concentration in plants and parameters of secondary metabolism - total phenolic content (TPC) and total antioxidative activity (TAA) were measured. Results showed that CDs based on folic acid were transported through maize and were present in both roots and leaves after 7 day-treatment. Cu concentration in roots was higher in both Cu and Cu/ 500CDs treatments compared to the control. The application of CDs reduced Cu concentration at the root level, while no significant effect was observed in leaves. However, the application of CDs was not effective in the mitigation of the oxidative stress in both roots and leaves induced by excess Cu. CDs neither affected TPC nor alleviated the TPC increase caused by Cu. Also, CDs did not cancel the TAA increase induced by Cu in any of the applied concentrations. In the leaves, TAA increased in all treatments when Cu was present in the growth medium. There were no visual adverse effects on plants.

abstract = "Copper (Cu) is an essential microelement in various processes in the cell wall, such as wall synthesis and loosening, but Cu excess due to human activities increase soil pollution and can induce harmful effects. Alleviation of Cu toxicity could be ameliorated in various ways such as adding organic compounds and cations (Ca2+, Mg2+). This study aimed to reduce Cu toxic effects using organic nanoparticles as potential nano-fertilizers obtained from folic acid. Carbon dots (CDs) are biocompatible and non-toxic nanoparticles with chemical affinity to some heavy metals. In this research, CDs were applied in two different concentrations - 167 mg/L and 500 mg/L with or without 5 µM Cu2+ during the growth of maize plants in hydroponic solution. Cu concentration in plants and parameters of secondary metabolism - total phenolic content (TPC) and total antioxidative activity (TAA) were measured.

AB  - Plants accumulate and synthesize various compounds, which are involved in plant-environment interaction. Among them are semi-volatile organic compounds of which 1700 are currently known to be emitted by plants. These compounds present 1% of plant secondary metabolites. The effect of cerium oxide nanoparticles (nCeO2) on semi-volatile organic compounds in plants was not investigated. Redox properties of nCeO2, based on their facile transition between Ce3+ and Ce4+ oxidation states are the main reason for their increased usage in the pharmaceutical industry, paints, cosmetics, electronics, and fuel additives. For that reason, nCeO2 can be found in the environment so there is a need to analyze their ecotoxicity. To improve their solubility, nCeO2 were coated with monosaccharide - glucose and microbial exopolysaccharides – levan, and pullulan. The main aim of this research was to study the effect of 200 mg/L glucose-, levan-, and pullulan-coated nCeO2 (G-CeO2, L-CeO2, and P-CeO2) in the shoot extracts of wheat and pea by screening the semi-volatile compounds with comprehensive two-dimensional gas chromatography (GC×GC-MS). The nCeO2 were applied at a concentration of 200 mg/L during three weeks of plants’ growth in hydroponics. The semi-volatile organic compounds were extracted from plant shoot extracts with methylene-chloride. Noticed coated nCeO2 effect was compared with the effect of uncoated ones. Nonlinear principal component analysis (NLPCA) with optimal scaling was used for the evaluation of wheat and pea GC×GC chromatograms and the confirmation of differences in chemical composition between untreated and treated plants. Results revealed that wheat samples had a higher number of chemical compounds than a pea. The chemical composition of wheat was less affected by the treatments with coated nanoparticles compared to pea. Most compounds which content was significantly different compared to the control compounds were detected in wheat after the treatment with L-CeO2 and P-CeO2, and in pea after L-CeO2 treatment. A semi-volatile profile was presented only as categorical variables, while unique fingerprint images were used for the inter-cultivar recognition. These results showed that GC×GC-MS as a screening method may be useful for monitoring the effects of various abiotic factors on different plant species.

AB  - A promising method for removal of Cs ions from water and their incorporation into stable crystal structure ready for safe and permanent disposal was described. Cs-exchanged X zeolite was hot-pressed at temperature ranging from 800 to 950 degrees C to fabricate dense pollucite ceramics. It was found that the application of external pressure reduced the pollucite formation temperature. The effect of sintering temperature on density, phase composition and mechanical properties was investigated. The highest density of 92.5 %TD and the highest compressive strength of 79 MPa were measured in pollucite hotpressed at 950 degrees C for 3 h. Heterogeneity of samples obtained at 950 degrees C was determined using scanning electron microscopy. The pollucite hot-pressed at 950 degrees C had low linear thermal expansion coefficient of similar to 4.67 x 10(-6) K-1 in the temperature range from 100 to 1000 degrees C.

AB  - Reports about the influence of cerium-oxide nanoparticles (nCeO(2)) on plants are contradictory due to their positive and negative effects on plants. Surface modification may affect the interaction of nCeO(2) with the environment, and hence its availability to plants. In this study, the uncoated and glucose-, levan-, and pullulan-coated nCeO(2) were synthesized and characterized. The aim was to determine whether nontoxic carbohydrates alter the effect of nCeO(2) on the seed germination, plant growth, and metabolism of wheat and pea. We applied 200 mgL(-1) of nCeO(2) on plants during germination (Ger treatment) or three week-growth (Gro treatment) in hydroponics. The plant response to nCeO(2) was studied by measuring changes in Ce concentration, total antioxidative activity (TAA), total phenolic content (TPC), and phenolic profile. Our results generally revealed higher Ce concentration in plants after the treatment with coated nanoparticles compared to uncoated ones. Considering all obtained results, Ger treatment had a stronger impact on the later stages of plant development than Gro treatment. The Ger treatment had a stronger impact on TPC and plant elongation, whereas Gro treatment affected more TAA and phenolic profile. Among nanoparticles, levan-coated nCeO(2) had the strongest and positive impact on tested plants. Wheat showed higher sensitivity to all treatments.

AB  - Dioscorea balcanica Košanin, family Dioscoreaceae, is an endemic,
endangered liana species and a Tertiary relict of Balkan Peninsula. Gelatinous fibers,
specialized sclerenchyma cells and well-known components of tension wood, are
responsible for stem twining in liana plants. The aim of this investigation was to
determine changes in sclerenchyma cell walls correlated with the twining process in
liana plants. Our results showed that the differences in cell walls of sclerenchyma cells
between straight and twisted internodes are not visible by light microscopy, but they
are visible by SEM microscopy. In twisted internodes, cell walls of sclerenchyma cells
in the region of contact with the support (‘‘tension’’ side of twisted internodes) appear
smooth on the cross sections, suggesting cellulose microfibrils oriented almost
parallel to the fiber axis. In contrast, cell walls of the entire ring of sclerenchyma cells
in straight internodes, as well as cell walls of sclerenchyma cells on the “opposite”
side of twisted internodes, appear jagged on the cross sections, suggesting cellulose
microfibrils oriented at very high microfibril angle to the fiber axis. This result
suggests that gelatinous fibers in D. balcanica stem have lignified G-layer, and thus
could contribute to the understanding of ‘‘late lignification of the G-layer’’.

AB  - Cerium oxide nanoparticles (nCeO2) are nanomaterial with various applications in biomedicine, electronics and cosmetics. The aim of this research was to improve their low suspension stability by coating with carbohydrates - glucose, levan, and pullulan. The coating was performed at different temperatures and coating times, by adding the carbohydrates during or after the synthesis of nCeO2. Characterization of nanoparticles’ powders was performed by X-Ray diffraction analysis, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Nanoparticles’ suspension stability was estimated by measuring of zeta potential, hydrodynamic size and turbidity. The difference among coated nCeO2 have been confirmed with FT-IR spectra. The results showed improved stability of the nCeO2 suspension and decreased size of aggregates after carbohydrate coating. Levan- and glucose-coated nCeO2 suspensions showed the best stability. The obtained nCeO2 were used for the investigation of their ecotoxicity on different plant species.

AB  - Carbon dots (CDs) are popular and emerging nanomaterial which found application in many fields such as drug delivery, optoelectronic, and imaging due to their high solubility, low cost and easiness of their functionalization. Their effect on plants is not sufficiently investigated, so it is necessary to investigate their ecotoxicity. In this research, CDs prepared from folic acid was used for the treatment of maize plants with two different concentrations. The treatment was performed during the plant growth in hydroponics. ICP method was used for the analysis of macronutrients (Ca, K, Mg, P, S) uptake in plants from the hydroponic medium, which was used for the plant growth. The obtained TPC results demonstrated low oxidative stress proportional to the used concentration, which was not significant. The similar trend was observed in TAA where the only significant increase was in plant shoots after the treatment at 500 µg L-1.

AB  - Cerium oxide nanoparticles (nCeO2) are biomaterials with numerous applications in biomedicine, fuel additives and electronics. Since their low stability in aqueous media limited their practical application, the aim of this study was to improve the suspension stability of nCeO2 by coating the particles. Glucose, monosaccharide, and levan and pullulan, microbial polysaccharides, were used as coating material. The coating was attempted under different synthesis conditions, by adding the carbohydrates during (direct coating) or after (subsequent coating) the synthesis of nCeO2. X-Ray diffraction analysis, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used for characterization of nanoparticles’ powders. Measuring of hydrodynamic size, zeta potential and turbidity was used for the estimation of nanoparticles’ suspension stability in aqueous media. The success of subsequent coating with carbohydrates and the differences between coated nCeO2 have been proven with FT-IR spectra. Turbidity measurement showed the best stability of levan- and glucose-coated nCeO2 suspensions. It can be concluded that coating with carbohydrates improved the stability of the nCeO2 suspension by decreasing the size of aggregated particles. The obtained results open new horizons for further ecotoxicity investigation and nCeO2 application.

AB  - Diatomaceous earth is of sedimentary origin consists mainly of accumulated skeletons formed as a protective covering of the diatoms. Usually, high absorption capacity of diatomaceous earth provides its wide use as heat insulation, filter, and absorbent material. Starting raw material, diatomaceous earth from surface coal mine Kolubara, Serbia, was characterized using X-ray fluoroscence (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM) were employed to the phases and microstructure of the diatomaceous earth. In addition, concentrations of activity of natural radionuclides 40K, 226Ra and 232Th and anthropogenic radionuclide 137Cs in diatomaceous earth were determined by gamma spectrometry with HPGe detector. It was found that the activity concentrations were in the range of 150-190 Bq / kg for 40K, 5-12 Bq / kg for 226Ra and 22-33 Bk / kg for 232Th. In all samples, the concentration of anthropogenic radionuclide 137Cs was below the detection limit. This research shows that this material is environmentally safe for further use.

AB  - DP-LS microscopy is a useful and easily applicable technique for rapid screening
of cell wall structural order, by mapping the linear dichroism of cellulose fibrils.
It allows screening and quantification of the alignment of cellulose fibrils, relative
to one another, in cell walls. The goal was to provide new information about
structural characteristics of the isolated cell walls among species which may be a
basis for their possible applications, such as biofuel and biomaterial industry, but
also to understand what plant response to stress is.
The DP-LSM method is shown to be a simple and rapid way to check the structural
complexity in the cell wall through cellulose labeling.

AB  - Ćelijski zid vlakana drveta može se smatrati kao nano-kompozit, u kojem su celuloza,
lignin i hemiceluloze kompleksno povezani. Organizacija i svojstva polimera drveta u
velikoj meri određuju svojstva vlakana i drveta, pa je i razumevanje interakcija između
ovih polimera ključ za genetski razvoj poboljšanog drveta i kvaliteta vlakana.1
Polarizovana FTIR mikro-spektroskopija se pokazala kao korisno sredstvo u proceni
anizotropije, odnosno orijentacija polimera ćelijskog zida u strukturi vlakna.2 Orijentacija
celuloze, glukomanana, ksilana i lignina, kao suštinskih komponenti drveta, tako može
biti analizirana u odnosu na osu vlakana. Ispitivane su strukturne razlike između tvrdog i
mekog drveta na primeru grana javora (Acer platanoides L.) i Pančićeve omorike (Picea
omorika (Pančić) Purkyně). Pokazano je da su hemiceluloze orijentisane paralelno u
odnosu na vlakna celuloze, tj u odnosu na osu ćelijskog zida. Takođe, kao važan rezultat
je dobijeno da je lignin i kod javora i kod Pančićeve omorike paralelno orijentisan u
odnosu na osu, kao i na celulozu. I pored različitih prekursora lignina i različitih
hemiceluloza kod ove dve vrste drveta lignin ima sličnu orijentaciju.

AB  - Cerium oxide nanoparticles (nCeO2) have been widely investigated because of their unique property - transition between Ce3+ and Ce4+ oxidation states which allows them multiple applications, such as a catalyst, an electrolyte material in fuel cells, for drug delivery, in agriculture (fertilizer, pesticides) etc. Despite these facts, the main restriction of nCeO2 application is their tendency for agglomeration, which led many researchers to coat them with different polymers. But literature data about the impact of coated nanoparticles on plant metabolism are scarce. Also, enhanced nCeO2 application has become the risk for the environment due to their accumulation in soil, air and water. Metal toxicity may lead to overproduction of reactive oxygen species (ROS) causing the  abiotic stress and damage of important biological molecules in crop species.
In current research, we performed a three week treatment of wheat and pea seedlings in hydroponics with 200 mgL-1 uncoated and glucose-, levan- and pullulan coated nCeO2 (G-CeO2, L-CeO2 and P-CeO2). Our goal was to study the impact of nanoparticles coating on Ce uptake, and on changes in total phenolic content (TPC), as indicator of oxidative stress, in monocotyledonous and dicotyledonous crop species. ICP-OES was used for determination of Ce concentration in shoots of treated crop species.
The uptake of Ce was different among treated crop species. Ce uptake was increased after coating in pea, but decreased in wheat. High Ce content detected in wheat, caused the increase in shoot elongation without the effect on TPC. On the other hand, low Ce content measured in pea, had  no influence on shoot elongation as well as TPC. 
Presented results suggest the difference in nCeO2 uptake and their effect on morphological parameters of plant without the impact on phenolic metabolism. Despite these results, further research is necessary.

AB  - Cerium oxide nanoparticles (nCeO2) are interesting due to redox property - transition between Ce3+ and Ce4+ ions. Increased usage of nCeO2 may raise its content in the environment, i.e. accumulation in water, air and soil. In many studies nCeO2 was coated with different polymers, but data on the effects of coated nCeO2 on crop species are scarce.
In this study, wheat and pea seeds were exposed to 5 day treatment with 200 mg/L uncoated and glucose-, levan- and pullulan-coated nCeO2 during germination. After three weeks of seedlings growth in hydroponics, phenolic profile in shoots was examined.
HPLC profiles showed unchanged qualitative composition (type and number of phenolics) in both tested plants. Among 5 identified phenolics, changes in peak areas were observed only in the most dominant phenolic-vicenin 1 in wheat, and in 3 phenolic compounds in pea. Results indicate minor changes of plants’ phenolic metabolism.

AB  - Biofilm-forming bacteria are recognized as a major impediment to wound healing. The aim of this study was to improve design of the formulations used for care of biofilm-infected wounds. Since lignins and lignin-derived compounds are known to have antibacterial properties especially efficient against biofilm-forming pathogens, the gel and membrane type of materials of enzymatically synthesized lignin model compound, dehydrogenative polymer of coniferyl alcohol (DHP) with alginate (Alg) and bacterial cellulose (BC) synthesized by culture Komagataeibacter intermedius IMBG180, were composed. The hydrogels were tested on Gram-negative P. aeruginosa (ATCC 27853) and S. typhimurium (ATCC 13311), Gram-positive bacteria L. monocytogenes (NCTC 7973) and S. aureus (ATCC 6538), as well as S. aureus #1*, S. aureus #2*, P. aeruginosa* and Serratia sp.* clinical human isolates obtained from patients’ wounds. DHP-Alg showed activity against all ofthe tested bacteria with minimal inhibitory concentrations (MICs) of 0.002–0.45 mg/mL and minimal bactericidal concentrations (MBCs) of 0.004–0.90 mg/mL. L. monocytogenes was the most susceptible. DHP-BC exhibited antibacterial activity on all tested bacteria, with exception of P. aeruginosa and S. aureus #1*. MICs and MBCs were in range of 0.22-0.42 mg/mL and 0.22-0.88 mg/mL, respectively. DHP-Alg gel and DHP-BC membranes, after initial release in the first hour of 34% and 19.26% of DHP, respectively, allowed the slow and continuous release of DHP in PBS solution. After 24 hours the amount of released antimicrobial substance from DHP-Alg and DHP-BC were 42.13% and 46.2%, respectively. Based on all obtained results, both hydrogels have the potential to be used in medical treatments as antibacterial agents.

AB  - Cerium oxide (CeO2) nanoparticles (CONPs) are interesting biomaterials with various applications in biomedicine, cosmetics and the pharmaceutical industry, but with limited practical application because of their low stability in aqueous media. The aim of this study was to obtain CONPs with increased stability by coating the particles. Microbial exopolysaccharides (levan, pullulan) and glucose were used to prepare CONPs under different synthesis conditions. Coating was attempted by adding the carbohydrates during (direct coating) or after (subsequent coating) the synthesis of CONPs. The obtained nanoparticles were characterized by X-Ray diffraction analysis, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The suspension stability of the uncoated and coated CONPs in aqueous media was evaluated by measuring the hydrodynamic size, zeta potential and turbidity. The FT-IR spectra revealed the differences between coated CONPs and showed the success of subsequent coating with carbohydrates. Coating with carbohydrates improved the stability the CONP suspension by decreasing the size of aggregated particles. The suspensions of levan- and glucose-coated CONPs had the best stability. In this study, CONPs were prepared using non-toxic materials, which were completely environmentally friendly. The obtained results open new horizons for CONP synthesis, improving their biological applications.

AB  - Lignins and lignin-derived compounds are known to have antibacterial properties. The wound healing agents in the form of dressings produce faster skin repair and decrease pain in patients. In order to create an efficient antimicrobial agent in the form of dressing in the treatment of chronic wounds, a composite hydrogel of bacterial cellulose (BC) and dehydrogenative polymer of coniferyl alcohol (DHP), BC-DHP, was designed. Novel composite showed inhibitory or bactericidal effects against selected pathogenic bacteria, including clinically isolated ones. The highest release rate of DHP was in the first hour, while after 24 h there was still slow release of small amounts of DHP from BC-DHP during 72 h monitoring. High-performance liquid chromatography coupled with mass-spectrometry showed that BC-DHP releases DHP oligomers, which are proposed to be antimicrobially active DHP fractions. Scanning electron microscopy and atomic force microscopy micrographs proved a dose-dependent interaction of DHP with BC, which resulted in a decrease of the pore number and size in the cellulose membrane. The Fourier-transform infrared absorption spectra of the BC-DHP showed that DHP was partly bound to the BC matrix. The swelling and crystallinity degree were dose-dependent. All obtained results confirmed BC-DHP composite as a promising hydrogel for wounds healing.
