Food quality and safety issues are among the most pressing and important for manufacturers, retailers, and end consumers. However, the development of pathogenic microorganisms in such products not only reduces their shelf life but also causes the development of infectious diseases in consumers. Therefore, there is currently an urgent need Читати далі

Previously, the authors isolated from the intestine of the chestnut moth caterpillars two cultures of bacteria – Pseudomonas putida and Escherichia coli. Since in interactions with plants or other living beings, lipopolysaccharides are involved, earlier we have characterized the lipopolysaccharide of one of the strains – Pseudomonas putida. The aim Читати далі

Under soil conditions, bacteria interact with nanoparticles of natural nanomaterials and ions. The study of such interaction and its effect on ATPase activity of bacteria is an important issue contributing to the understanding of the mechanisms underlying the functioning of living cells in their interaction with nanomaterials. Objective. To investigate Читати далі

Biosensorics is a new branch of analytical biotechnology, one of the main directions of which is the development of electrochemical biosensors. Microorganisms capable of bioluminescence are often used in biosensor systems. Such microorganisms include marine bioluminescent bacteria Aliivibrio ficsheri, Vibrio campbellii, Vibrio harveyi, Photobacterium phosphoreum, etc. Since these marine microorganisms Читати далі

The amount of precipitation and its seasonal distribution affect the contamination of grain fodder with micromycetes. The use of grain from different crops as animal feed and in the food industry raises concerns about its quality and adherence to sanitary and medical standards. The aim of this study was to Читати далі

Avian pathogenic Escherichia coli (APEC) is a widely distributed pathogen and one of the main death causes in poultry farming. Also, these bacteria are harmful food-born pathogens with multiple virulence factors and pathogenicity that could be dangerous for humans. Moreover, APEC is characterized by a wide range of resistance to Читати далі

In recent years, in regions of intensive agriculture, due to unfavorable agro-ecological conditions, mixed infections have become a serious threat to the production of high-quality crop products, in particular, Galega orientalis L. Objective. To investigate the effect of mono- and mixed phytoplasma and bacterial infection on Galega orientalis L. plants. Читати далі

During the growth and development of plants, a large quantity of root exudates is released into the rhizosphere, forming a microbiome capable of stimulating plant growth and productivity. The application of microbial preparations will be the cornerstone of soil improvement and obtaining high-quality plant products. The aim of this study Читати далі

Previously, elastase activities have been found in some microorganisms and presented by metalloproteases, which may play an important role in helping bacterium invasiveness and establishment of infection. The elastases from Bacillus species are serine proteases, however, to date there are few reports on systematic study of these enzymes producers among Читати далі

As known, walnut is vulnerable to various pathogenic microorganisms, in particular bacteria that can cause significant lesions during their cultivation. Over the last decade, causative agents of walnut's bacterial diseases, which previously did not affect this culture, have been discovered all over the world. The expansion of the spectrum of Читати далі
