The main interest in the study of marine microorganisms is due to their ability to produce a wide range of unique enzymes, including peptidases with different specificities. In recent years, interest has increased in peptidases that are able to cleave elastin as a specific substrate. Streptomyces fradiae and Bacillus thermoproteolyticus Читати далі

The specifics of the processing of livestock and poultry products is that in the process of obtaining the main marketable products, about half the feedstock at various stages of the technological process turns into waste that pollutes the environment. These by-products contain large amounts of the hard-to-digest keratin protein. The Читати далі

Giant viruses (GV) are widespread in various ecosystems and ecological niches of the biosphere, most commonly in marine and freshwater aquatic ecosystems and soils. These viruses infect protists, a paraphyletic group of various unicellular, syncytial, and protozoan multicellular eukaryotes that are not true animals, plants, or fungus. The morphologically and Читати далі

α-L-Rhamnosidase (α-L-rhamnoside-rhamnohydrolase EC 3.2.1.40) showing specificity for terminal α-1,2-, α-1,4- and α-1,6-linked rhamnose residues, which often present in glycoconjugates and synthetic glycosides, can be successfully used in biotechnology for the hydrolysis of rhamnopyranoside residues present in some bioflavonoids, glycoproteins, glycolipids, and other glycoconjugates. Previously, we have shown that a significant Читати далі

Recently, there has been a trend toward the use of new effective natural preparations to fight diseases and improve the health of honey bees. It is also known that a well-balanced structure of the intestinal microbiota of honey bees is the basis for their growth, development, strengthening of the immune Читати далі

Currently, the effectiveness of technologies for microbial surfactants, which are characterized by a complex of practically valuable physicochemical and biological properties is lower than that of synthetic analogues. To reduce the cost of these products of microbial synthesis, industrial waste is used as substrates for their biosynthesis. In previous studies, Читати далі

Green synthesis of nanoparticles (NPs) using living cells is a promising and new tool in bionanotechnology. Chemical and physical methods are used to synthesize NPs, but biological methods are preferred because of their environmentally friendly, clean, safe, cost-effective, simple, and efficient sources for high productivity and purity. Aim. To investigate Читати далі

African swine fever (ASF) remains an urgent problem of pig farming in Ukraine, the solution of which is possible only on the basis of deep scientific knowledge about the specific driving forces of the epizootic in its specific nozoareal. This is necessary in order to target anti-epizootic measures on the Читати далі

Today, the search for safe ways to inactivate pathogens is becoming especially relevant in connection with the coronavirus pandemic. Standard methods using chlorides and ultraviolet irradiation have disadvantages related to toxicity and low efficiency. Photodynamic inactivation involving nanoparticles is already used to disinfect water and air from microorganisms and enveloped Читати далі
