In the course of studies of physiological and biochemical features and some mechanisms of antibacterial action of yeast on the growth and aggregative behavior of bacteria, regularities in therelationship between the processes of motility and the characteristics of biofilm formation of model pseudomonas were revealed. Using the methods of mathematical statistics (BWP), the peculiarities of the effect of glucose and xylose on the growth and fermentation activity of representatives of the genusSaccharomycetaceae – yeast Scheffersomyces stipitis UCM Y-2810, which is capable of fermenting xylose, were established. The resistance of 1364 yeast strains from the Ukrainian Collection of Microorganisms to salt, osmotic stress and acetic acid was determined, and differences in the level of resistance of different taxonomic groups of yeast to stress factors were revealed. The peculiarities of the interaction of yeast cells with mammalian cells have been established. The role of flocculin genes FLO11 and CWP1 in the communication of yeast and mammalian cells has been proven. The role of EMR and the participation of phosphorus metabolism in these processes have been clarified. 25 exopolysaccharides (EPS) produced by strains of lactic acid bacteria have been isolated and characterized. EPS have a molecular weight in the range of 37.5-50 kDa and contain mainly glucose (85-97%). The ability to produce EPS depended on the source of isolation and taxonomic position. Most often, EPS producers were isolated from pickled apples and these are representatives of the genera Leuconostoc and Pediococcus. The vast majority of bacteria produced EPS when grown on a medium with sucrose in quantities of 1-18 g/l. It was shown that the EPS of lactic acid bacteria inhibited the biofilm formation of the studied test cultures of phytopathogenic microorganisms.
