Relevance. Microscopic fungi exhibit the greatest exoenzymatic activity, and xylotrophs are capable of possessing a complex of oxidase and hydrolase enzymes to destroy lignin. Methods. Among the soil micromycetes isolated from the rhizosphere of annual leguminous crops, a search was made for strains that are promising from the point of view of effective microorganism technology, in order to create optimal conditions for increasing soil fertility and crop yields. The detection of total phenol oxidase activity was carried out according to the method of Bavendamm, cultivating the strains on microbiological agar with the addition of an aromatic lignin derivative (0.06% tannin) and the growth factor was calculated. The cellulase activity of the strains was judged by the degree of hydrolysis of the filter paper. Alternaria alternata, Bipolaris, Botrytis fabae, Cunninghamella echinulata, Curvularia lunata, Macrophoma phaseolicola, Trichoderma koningii, Trichoderma viride and Ulocladium botrytis strains were found to cleave lignin and cellulose...
