Документ Biosynthesis of silver nanoparticles using Acinetobacter calcoaceticus ІМV V-7241 cell-free supernatant(2020) Laziuka, Yuliya; Kharchenko, Yevgen; Skrotska, OksanaCurrently, the biological synthesis of nanoparticles and their properties and application in the fields of medicine and the environment is an important area of nanotechnology. Synthesis of nanoparticles using chemical and physical methods has several disadvantages. These drawbacks include the use of toxic solvents, the formation of dangerous by-products and high energy consumption. Therefore, it is important to obtain nanoparticles in a biogenic way, in particular by microorganisms. The mechanisms of biogenic synthesis of nanoparticles have not been fully studied. There are reports on the role of surface active agents (surfactants) in this process. Therefore, the producer of surfactants Acinetobacter calcoaceticus ІМВ В-7241 (which was isolated from the oil contaminated environment) was selected for the study.Документ Biosynthesis of recombinant interferons in transgenic plants(2017) Holubiev, Pavlo; Kharchenko, Yevgen; Skrotska, OksanaThe production of recombinant cytokines with transgenic plants may solve the problem of high demand on drugs against severe diseases, such as hepatitis, AIDS, chronic granulomatous disease, etc. Microorganisms, mammal cell cultures and even plants may be involved in interferon (IFN) production. Considering an array of disadvantages of microbial and mammalian cell cultures, transgenic plants become an object of interest as a perspective producer of interferon.Документ Saccharomycetes as biological agents for the mediated biosynthesis of silver nanoparticles(2021) Kharchenko, Yevgen; Skrotska, OksanaThe most commonly used are chemical and physical methods of silver nanoparticles (AgNPs) synthesis, but there is also biological synthesis, which is a promising and more environmentally friendly method. Synthesized using the supernatant Saccharomycescerevisiae M437 AgNPs had a spherical shape. AgNPs that were obtained using a cell-free aqueous extract of S. cerevisiae M437 had an oval shape.
