Bacteria of the Bacillus genus can synthesize specific phytase enzymes. This property is especially important for soil bacteria. It helps to mineralize phytin and phytates and to provide these bacteria and plants (in the root zone of which they live) with the available phosphorus. Our previous studies have demonstrated that Читати далі

Numerous studies in recent years have shown that the gut microbiome plays an important role in maintaining various physiological processes in the body, including digestion, metabolism, immune system function, defense against pathogens, biosynthesis of unique metabolites, elimination of toxins, and regulation of the function of the gut-brain axis. The gut Читати далі

The world’s energy sector has undergone drastic changes in the last decades due to the climate change and the turn to renewable energy sources. Biomass is the largest renewable source of carbohydrates on the Earth and is an important substrate for biofuel production. Saccharomyces cerevisiae yeasts are the main producer Читати далі

The deposited by us highly active bacteriocin producer Pseudomonas aeruginosa UСM B-333 synthesizes pyocins, which intensively inhibit phytopathogenic strains of Pseudomonas syringae — plant pathogens. This strain produces pyocins S1 and S5, as well as microcin-II-like bacteriocins. The aim of this work was to check the presence of other pyocins Читати далі

Today, one of the topical areas of research is the search for antiviral drugs to fi ght against virus-associated oncological manifestations. One of the viruses for which a role in the transformation of cells is proved is Epstein-Barr virus (EBV), which is associated with a variety of lymphoproliferative diseases. The Читати далі

The increase in the number of resistant strains of Candida genus representatives, capable of forming biofilms on various surfaces, stimulates the search for new, alternative methods of combating them, one of which is the use of compounds of natural origin, such as essential oils. However, at the same time, their Читати далі

In recent years, the particular interest of researchers is focused on such enzymes as α-L-rhamnosidase and α-galactosidase. These enzymes are considered useful for various applications. α-L-rhamnosidases may be applied for debittering of citrus fruit juices, due to the less bitter taste of the derhamnosylated flavonones, for rhamnose production, and for Читати далі

This review examines current knowledge on the prevalence of weeds and feral grass specie as possible reserves of plant viruses in the agroecosystems of Ukraine. Studies concerning mainly virus infection of wheat and barley and weeds distributed in the agrosystems of cereal crops and their impact on virus epidemiology have Читати далі

Hydrolysis of lignocellulose to fermentable sugars and their subsequent conversion to ethanol remain great challenges in the biofuel industry. Rotten wood is first colonized by bacteria and molds that possess strong hydrolases. Yeasts are also an important group of microorganisms that may participate in wood hydrolysis. Decaying wood could provide Читати далі

<p style="text-align: justify;">Antiseptics are non-specific antimicrobial drugs that are widely used in dentistry. The "gold standard" in periodontology is chlorhexidine digluconate (CHG). A widespread use of CHG-containing products for daily care in medicine and dentistry and other fields leads to acquiring resistance to CHG in microorganisms. A macro method of Читати далі
