The dependence-of changes in the electrooptical properties of Azospirillum brasilense cell suspension Sp7 during interaction with bacteriophage ΦAb-Sp7 on the number and time of interactions was studied. Incubation of cells with bacteriophage significantly changed the electrooptical signal within one minute. The selective effect of bacteriophage ΦA...

The peroxidase and catalase activities in the mycelium of luminous basidiomycetes Armillaria borealis and Neonothopanus nambi in normal conditions and under stress were compared. An increase in the luminescence level was observed under stress, as well as an increase in peroxidase and catalase activities. Moreover, the peroxidase activity in extract...

In this study we investigated the activities of antioxidant enzymes (superoxide dismutases (SODs) and catalases (CATs)) and the ROS level in cells of Yarrowia lipolytica yeasts grown in a medium with different pH values (4.5, 5.5 and 9.0). It was shown that an increase in the cellular ROS level took place under both acid and alkaline conditions. Th...

The effect of polysaccharide monooxygenase (endoglucanase IV) from the fungus Trichoderma reesei on the hydrolysis of polysaccharide substrates by cellulases secreted by the fungus Penicillium verruculosum has been investigated. Supplementation of the enzyme complex from P. verruculosum by endoglucanase IV from T. reesei has been shown to elevate t...

Data from the literature and our own data on the participation and interrelation of bacterial signaling Nod-factors and components of the calcium, NADPH-oxidase, and NO-synthase signaling systems of a plant at the preinfection and infectious stages of the formation of a legume-rhizobium symbiosis are summarized in this review. The physiological rol...

A new method of controlling lactic acid bacteria contamination was developed with the use of recombinant Saccharomyces cerevisiae strains producing antibacterial peptides. Genes encoding the antibacterial peptides pediocin and plantaricin with codons preferable for S. cerevisiae were synthesized, and a system was constructed for their secretory exp...

We demonstrated that a change in the catalytic activity of fungal lipases synthesized by Rhizopus microsporus, Penicillium sp. and Oospora lactis and their ability to absorb on different sorbents depended on the nature of groups on the solid phase surface in the model systems water: lipid and water: solid phase. Thus, the stability of Penicillium s...

A test system based on immunochromatography in the sandwich format and intended for express detection of Helicobacter pylori antigens has been developed. Contact of a sample with a test strip coated with immunochemical reagents triggers the movement of the liquid along the membrane components of the test strip, immunochemical interactions, and the ...

Microbial dehalogenation is a biochemical process in which the halogenated substances are catalyzed enzymatically in to their non-halogenated form. The microorganisms have a wide range of organohalogen degradation ability both explicit and non-specific in nature. Most of these halogenated organic compounds being pollutants need to be remediated; th...

We report the development of a heterogeneous biocatalyst for the hydrolysis of amides that is based on cell adhesion ofamidase-containing Rhodococci on activated birch carbon (ABC) and crude carbon. We investigated the properties of the obtained biocatalyst in the hydrolysis reaction of acrylamide to acrylic acid and nicotinamide to nicotinic acid,...
