To identify the ability of the isolated strains to destroy organic waste, their preliminary selection was carried out by cultivation on manure agar for 14 days. It was found that the most intensive use of organic residues in laboratory models of the medium was possessed by strains No. 1,3,4,5,6,7,11,12,14,15, 21, 32 Lactococcus, Trichoderma, Sacharomyces, Candida, Pseudomonas, Lactobacillus. They were used for further experiments. All the studied microorganisms have amylolytic activity: strains No. 1, 6, 8, 9 and 10 hydrolyze starch by 100%; strain No. 4 - by 94.4%; No. 5 - by 84.8%; No. 7 and 12 - by 92.3%; strains No. 2, 3 and 11 – by 83.3 and 47.2%. The most pronounced proteolytic activity is shown by strains № 2, 3, 4, 5, 7, 11 the width of the illumination zone ranged from 1 to 1.2 cm. Moderately pronounced proteolytic properties were noted in strains No. 6 and 8, the width of the enlightenment zone is from 0.4 to 0.5 cm. Strains No. 1, 9, 10 and 12 showed weak proteolytic properties. The zone of enlightenment of the medium during the growth of these microorganisms is practically absent. Of the isolated isolates, practically all microorganisms did not possess phytotoxic properties. Based on the conducted research, the selected strains of microorganisms will be used for possible biodegradation of organic waste in agriculture and for the greening of territories.
