Abstract

The purpose of research was to assess the possibility of using Trichoderma harzianum 857, isolated from the soil of Uzbekistan, as a source of cellulolytic enzymes for processing of cellulose-containing substrates. It was established that the fungus Trichoderma harzianum 857, due to the synthesis of extracellular cellulolytic enzymes, can be used for hydrolysis of cellulose-containing substrates (wheat straw). The conditions for pretreatment of the cellulose-containing substrate (temperature 100ºC, pressure 1 atm., time 1.5 h) were selected to increase the efficiency of its enzymatic cleavage. It was shown that adding ground green part of amaranth to a composition of cellulose-containing substrates contributes to the enrichment of the final product with protein, vitamins and trace elements, which makes it possible to use it as a high-protein product.
