Royal jelly has unique healing properties due to the presence of a number of biologically active compounds and yet unidentified components that are used for the prevention and treatment of many diseases. Purpose. To investigate the antimicrobial activity of homogenate of bee queen larvae and royal jelly against four phytopathogenic Читати далі

Any natural ecosystem contains a specific range of microorganisms. The anthropogenic impact can cause a change in the growth conditions of soil and rhizospheric microbiome and affect the number and the physiological properties of microorganisms. The aim of the study was to isolate the representative microorganisms from terrestrial ecosystems of Читати далі

For a long time, the main interest in the marine environment, considered extreme, was the isolation and identification of natural products with biological properties, and for that, numerous organisms and chemical structures have been studied. Thus, marine bacteria isolated from various substrates, such as sediments, seawater, and mangrove detritus, are Читати далі

In 1979, L.T. Pastushenko and I.D. Symonovych developed a scheme of serogrouping phytopathogenic bacteria of the Pseudomonas genus, which is still used now. However, today’s using this serogrouping scheme is complicated by the lack of all data accumulated over the years of its application. Moreover, the scheme does not correspond Читати далі

Viticulture is one of the most intensive and complex branches of Ukraine agriculture. Grapevine virus diseases are responsible for considerable economic losses to grape productivity and wine industries. One of the most notable and widespread viruses associated with vine leafroll disease is grapevine leafroll-associated viruses (GLRaV), belonging to the genus Читати далі

Azospirillum brasilense is a gram-negative, nitrogen-fixing bacterium that colonizes the rhizosphere of various types of grasses and cereals. Lipopolysaccharides (LPS) are a class of complex glycolipids present in the cell membrane of gramnegative bacteria and mediate plant-bacteria interactions. Although the effects of LPS of pathogenic plant bacteria on the induction Читати далі

Despite the fact that in recent years there has been a certain enhancing interest in the study of marine microorganisms, nevertheless, marine bacteria as producers of biologically active substances, in particular enzymes, are still poorly studied. The marine biota is significantly different from the terrestrial one; therefore, there is a Читати далі

The level of oxygen mass transfer (KV) is an important parameter influencing the growth rate of aerobic microorganisms and the synthesis of metabolites. It is mainly determined by the agitation and the aeration rates in the fermenter. Aim. To study changes in pH, optical density (OD), and hemagglutinating (lectin) activity Читати далі

Staphylococcus aureus is a widespread opportunistic pathogen, causing community-acquired and nosocomial infections with both acute and chronic recurrent courses. The process of chronicity of the disease is provided by biofilms. Features of the structure and functioning of biofilms, in particular the presence of matrix, quorum sensing systems, persistent cells, and Читати далі

Species of the genus Trichoderma are known as the producers of many biologically active substances, in particular, enzymes that have found their practical application in many industries. In addition, the active Trichoderma strains are used as biological control agents of plant pathogenic micromycetes. Trichoderma strains are able to exhibit antagonistic Читати далі
