The aim of the research is to determine the effect of the probiotic preparation «Dialak» (dietary supplement), which includes the strain Lactobacillus casei IMV B-7280, on the vaginal microbiota and humoral immunity in women with bacterial vaginosis (BV). Methods. 40 female patients aged 20—45 years with disturbed vaginal microbiota and Читати далі

The aim of the work is to identify strains of streptomycetes in the genomes of which there are nucleotide sequences similar to the gene cluster determining the synthesis of landomycin A (lan-cluster) and establish the level of similarity of their primary structures and organizations. Methods. Information on the sequences of Читати далі

The intensive development of biotechnology in the last decade is largely determined by the growing requirement needs of both medicine and various industries for products of microbial synthesis, including glycosidases, in particular α-L-rhamnosidases. Their wide use to solve current biological-medical and chemical-technological problems stimulates researchers to search for compounds capable Читати далі

Aquaculture (especially fish farming) provides billions of people with nutrients: amino acids, vitamins, minerals, and proteins. Aquaculture of commercial species (rainbow trout, common carp, grass carp, pacific white-legged shrimp, etc.) are growing rapidly and accounts for about a third of the global fish production. It is a major alternative to Читати далі

The search for effective and environmentally sound measures to fight against plant diseases caused by phytopathogenic microorganisms is of great importance. It is especially important to investigate alternative measures to protect cultivated plants that combine elements beneficial to human health such as iodine and selenium. Purpose. The study of physiological Читати далі

In recent years, one of the important goals is to develop information systems for continuously monitoring the biological impact of the variable geomagnetic field. This problem is of importance from the viewpoint of forecasting such global processes as climate changes as well. Objective. This study is focused on monitoring the Читати далі

Lignocellulosic biomass can be utilized as a low-cost, renewable, and sustainable feedstock for obtaining non-fossil energy sources with low CO2 emission. One of the most promising technologies for producing 2G biofuels is the saccharification of agricultural waste materials with the help of cellulolytic enzymes, followed by yeast fermentation of sugars Читати далі

The efficiency of the introduction of nodule bacteria, microsymbionts of legumes in agrocenoses, largely depends on the activity of biologically active substances’ biosynthesis by diazotrophs. Seed bacterization with effective rhizobia strains capable of synthesizing exometabolites for phytostimulating activity not only promotes the formation and functioning of symbiosis but also creates Читати далі

Zinc oxide nanostructures (NS) were grown on thin discontinuous films of noble metals of silver and gold in order to study their structure, optical properties as well as photocatalytic and antiviral activity. The paper presents the results of X-ray diffraction study, scanning electron microscopy study, photoluminescence and Raman measurements. X-ray Читати далі

Today, the antiviral activity of oxide nanomaterials can be used in the fight against the viral disease COVID-19. It is thought that Ag nanoparticles may bind to the surface glycoprotein of the virus and interfere with the virus’s interaction with epithelial cells, and inhibit virus reproduction by releasing silver ions Читати далі
