AB  - Plant pathogenic bacterium Xanthomonas campestris pv. campestris (Xcc) was recently described as a pathogen of winter oilseed rape in Serbia. A metabarcoding approach was used to study bacterial community composition changes in the phyllosphere and rhizosphere of different winter oilseed rape types (lines, cultivars, and hybrids) naturally infected with Xcc. This study also aimed to examine the potential of indigenous Bacillus and Pseudomonas isolates to suppress Xcc. Infection with Xcc leads to depletion of bacterial diversity in the plants' phyllosphere and explicitly decreasing the abundance of genera such as Exiguobacterium, Massilia, and Pantoea with potentially beneficial properties. Strains identified as Bacillus velezensis X5-2, Bacillus megaterium X6-3, and Pseudomonas orientalis X2-1P obtained from oilseed rape phyllosphere were found to be effective against Xcc in vitro and in vivo when applied as a whole-culture and as a cell-free supernatant. The greenhouse in vivo tests on winter oilseed rape plants with three selected biocontrol strains lead to a disease reduction of 82.37% and 72.47% in preventive and curative treatments, respectively. Genetic screening showed potential for the biosynthesis of surfactin, kurstakin, bacillomycin D, and iturin in B. velezensis X5-2, as well as surfactin and kurstakin in B. megaterium X6-3. Gene phcA encoding phenazine-1-carboxylic acid was detected in P. orientalis X2-1P. The chemical composition of ethyl acetate and benzene extracts of three biocontrol strains obtained by GC-MS and HPLC-ESI-qTOF/MS analyses indicates numerous volatile organic compounds (alkenes, benzenes, carboxylic acids, indoles, pyrazines, etc.), lipopeptides, and/or antibiotics, for many of which antimicrobial potential is proven. We assume that this wide range of metabolites is responsible for the exhibited biocontrol activity against Xcc. These results recommend all three biocontrol strains for further studies for use as agents for biocontrol of bacterial blight-like disease caused by Xcc of oilseed rape.

AB  - Winter oilseed rape has recently been described as a new host for the phytopathogenic bacteriumXanthomonas campestrispv.campestris(Xcc) in Serbia. In order to provide information about the genetic structure of this bacterium's population and its pathogenic features on this crop, a collection of 65 winter oilseed rape Xcc isolates obtained over a 5-year period (2014-2018) from different Serbian localities was examined. The presence of intrapathovar diversity within the tested isolates was confirmed by repetitive element PCR (rep-PCR), revealing 14, 10, and 4 different profiles for BOX, ERIC, and REP primers, respectively. A multilocus sequence typing (MLST) approach separated the isolates into seven groups on a phylogenetic tree. The PubMLST non-redundant database was used to compare sequences of four housekeeping genes from isolates with 75 strains ofXanthomonasspp. to determine nucleotide changes caused by host-pathogen coevolution. Five allelic profile combinations (ST3, ST5, ST9, ST26, and ST47) were determined, with ST47 being the most frequent. Pathogenicity and host range tests showed higher virulence of the tested isolates on winter oilseed rape than on otherBrassica oleraceahosts (broccoli, cabbage, cauliflower, collard greens, kale, and kohlrabi). The most aggressive isolates were NCPPB4679, NCPPB4680, and Xc361, belonging to genotype ST26. Fifty oilseed rape lines, cultivars, and hybrids showed susceptibility to the three Xcc isolates tested (of high, low, and moderate virulence), indicating that there was no resistance to the bacterium. The results provide significant information about diversification of Xcc isolates and their evolution toward specialization for winter oilseed rape.

AB  - The "Pirot 'ironed' sausage" (Pis) is a traditional, dry, fermented product originating from the town of Pirot, situated in southeastern Serbia. This product is made from different types of meat (goat, sheep, beef and donkey) and spices, without additives or starter cultures. Pis is an organic, unprocessed product, without heat or smoke treatment. The aim of this study was to characterize 120 isolates of lactic acid bacteria (LAB) from Pis produced by six different brands during a two-year period using phenotypic and genetic identification. Preliminary characterization of the LAB was based on general morphology and biochemical tests. Repetitive elements such as REP, BOX and GTG(5), found in the genome of these bacteria, and randomly amplified polymorphic DNA-polymerase chain reaction (RAPD PCR) sequences were used for determination of genetic polymorphism. Identification by 16S rRNA gene sequencing showed the presence of only two LAB species, Lactobacillus sakei (76%) and Leuconostoc mesenteroides (24%). However, genetic polymorphism was detected using fingerprinting methods. In comparison with other primers, the profiles obtained with GTG(5) showed the highest heterogeneity for most of the tested isolates, with sequencing results additionally confirming its discriminatory power. In addition, M13 RAPD primer also produced satisfactory separation of the tested isolates.

AB  - In vitro anti-tumour and anti-radical activities of the acetone extract of the freshwater sponge Ochridaspongia rotunda were the subject of this study. The extract was found to be highly cytotoxic to human lung tumour cell line A-549 reaching IC50 value of 5.01 +/- 0.21 mu g/mL. Indeed, it displayed only 2-fold less anti-tumour activity than doxorubicin (IC50 value 2.42 +/- 0.13 mu g/mL) used as a positive control. The same extract was also found to be almost 37-fold more selective against A-549 vs. MRC-5 (normal) lung cells, in difference to weak selectivity of doxorubicin (less than 3-fold). Its profound anti-DPPH radical activity comparable to that of quercetin (IC50 values 3.68 +/- 0.19 and 3.14 +/- 0.09 mu g/mL, respectively) coupled with no signs of genotoxicity in the comet assay (MRC-5 cell line, vs. doxorubicin) has actually implicated the importance of this animal bioresource in searching for pharmaceutically useful bioactive compounds of natural origin.

AB  - Context: Bioprospection has become a dynamic scientific field that explores novel possibilities for the implementation of natural products in medicine and pharmacy. Compared to marine species from all kingdoms, freshwater species have been highly neglected. Objective: This work focuses on the screening of acetylcholinesterase inhibitory (AChE) and mutagenic activities of the acetone extract (obtained by maceration) of the freshwater sponge Ochridaspongia rotunda Arndt (Malawispongiidae) in vitro. Materials and methods: AChE inhibitory activity was evaluated both in liquid (five different concentrations of the extract, from 1 to 100 mu g/mL) and in solid (seven different concentrations of the extract, from 0.5 to 10.0 mu g) by methods well described in literature, while mutagenicity was estimated using the Ames test (four different concentrations of the extract, from 0.106 to 1.328mg/plate). Results: Ochridaspongia rotunda acetone extract exhibited promising AChE inhibitory activity in a dose-dependent manner both in liquid (IC50 23.07 mu g/mL) and in solid (1.50 mu g). Furthermore, the Ames test revealed no sign of mutagenicity at any concentration tested. Its FTIR spectrum coupled with the positive Liebermann-Burchard, Salkowski and Zak color reactions (tests) indicated the presence of sterol compounds. Discussion and conclusion: The screened extract may inspire a search for novel anticholinesterase therapeutic agent(s) potentially used in the treatment of Alzheimer's disease. Further research will be directed toward its detailed chemical analysis along with addressing the issue of a real producer of the natural product(s) responsible for the AChE activity observed.
