Production of fructose and gluconic acid from sucrose with cross-linked yeast cell walls expressing glucose oxidase on the surface
(Elsevier B.V., 2022)
Saccharomyces cerevisiae, known as bakers’ yeast, is one of the most utilized yeasts in industry. Several enzymes that are naturally produced by yeast, such as invertase and catalase, combined with heterologously expressed ...
A novel and effective natural product-based immunodetection tool for TNT-like compounds
(Taylor & Francis Ltd, Abingdon, 2022)
This study aimed to develop a fast and reliable protocol for Trinitrophenol-Tris(hydroxymethyl)aminomethane (TNP-Tris) detection applying a beta-lactamase-fusion protein of choice, the natural product-based immunoreagent ...
3.5-scFv-beta-lactamase, a new protein detector of picric acid, the highly nitrated organic explosive
(Taylor & Francis Ltd, Abingdon, 2022)
A new protein detector of 2,4,6-trinitrophenol (TNP, picric acid) is concisely reported herein for the first time. In brief, the gene of a specific scFv fragment, namely 3.5, was fused separately with the gene of beta-lactamase ...
Structural and Morphological Properties of Indium-doped Titanium Dioxide Nanoparticles Synthesized Using Sol–gel Process
(Springer Science and Business Media Deutschland GmbH, 2022)
In this paper, we have investigated undoped and indium-doped titanium dioxide (TiO2) nanoparticles prepared using sol–gel method. The aim of this work is to analyse the effect of indium incorporation on the structure and ...
Comparative study of lignocellulosic biomass and its components as electrode modifiers for detection of lead and copper ions
(Elsevier Science Sa, Lausanne, 2020)
Cellulose, xylan and lignin, as well as maize cell wall, were used as modifiers of carbon paste electrode. Comparative analysis of electrochemical performance of each modifier toward heavy metal detection was performed. A ...
Lignin and organic free radicals in maize (Zea mays L.) seeds in response to aflatoxin B-1 contamination: an optical and EPR spectroscopic study
(Wiley, Hoboken, 2022)
BACKGROUND Aflatoxin B-1 (AFB(1)) is the most dangerous of the mycotoxins that contaminate cereal seeds naturally. A stress lignin formation is linked with the accumulation of reactive oxygen species causing a change in ...
Toxicity investigation of CeO2 nanoparticles coated with glucose and exopolysaccharides levan and pullulan on the bacterium Vibrio fischeri and aquatic organisms Daphnia magna and Danio rerio
(Elsevier, Amsterdam, 2021)
Cerium oxide nanoparticles (nCeO(2)) have widespread applications, but they can be hazardous to the environment. Some reports indicate the toxic effect of nCeO(2) on tested animals, but literature data are mainly contradictory. ...
Cell wall response to UV radiation in needles of Picea omorika
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2021)
The UV-B represents the minor fraction of the solar spectrum, while UV-C is not contained in natural solar radiation, but both radiation types can cause damaging effects in plants. Cell walls (CWs) are one of the targets ...
Seasonal variations of macro-, micro-, and toxic elements in tissues of vimba bream (Vimba vimba) from the Danube River near Belgrade, Serbia
(Springer Heidelberg, Heidelberg, 2021)
Vimba bream (Vimba vimba) individuals were collected from the Danube River near Belgrade, from May 2016 to May 2017. Samples of muscle and liver tissue were analyzed for concentrations of 25 elements (macro-, micro-, and ...
Flexible lead-free NBT-BT/PVDF composite films by hot pressing for low-energy harvesting and storage
(Elsevier Science Sa, Lausanne, 2021)
The idea of this work is finding the way to efficiently and safely use mechanical energy released in small quantities around us to power up small-scale electronic devices used in everyday life. To this purpose, flexible ...
