Complex processing of raw materials is a rational way to use the resources of medicinal plants. It was of interest to evaluate the expediency of using meal obtained after juice extraction from the grass of the common cuff, freshly harvested as a plant substance with the potential of a prebiotic. The purpose of this study was to study and evaluate the potential of bacteriotropic activity of common grass cuff meal. The chemical composition of meal samples contains flavonoids, tannins, polysaccharides, free amino acids and minerals capable of stimulating the growth and development of microorganisms. The stimulating effect of meal on the culture of lactobacilli is shown by a significant decrease in glucose levels in all samples compared with the control. The culture of lactobacilli reacted to the introduction of an infusion of grass meal into the nutrient medium by increasing the accumulation of biomass. It was found that all samples of the meal infusion have the property of inhibition with a pronounced dose-dependent effect on changing the luminescence level of the E.coli lum+ strain in the bioluminescence inhibition test when exposed for 4 hours. In the course of the research, the bacteriotropic properties of meal from grass cuffs have been identified, which determine its prospects for the correction and prevention of dysbiotic conditions by improving the functional potential of the human microbiota or farm animals and poultry. Within the framework of rational use of resources, it seems advisable to use meal as a plant substance with the potential of a prebiotic.
