Effective strains displaying glucoamylase activity have been obtained as a result of screening among the representatives of genera Acremonium, Alternaria, Eupenicillium, Gliocladium, Myrothecium, Penicillium, Rhizopus. However, the most active biosynthetics belong to Aspergillus, Fusarium and Phoma. The studies of a number of cultivation conditions of four Aspergillus sp. strains indicated that the optimum sources of carbon at its submerged cultivation were 2% potato or corn starch, and also the mixture of 2% potato starch with 1% maltose. The comparative effects of glucoamylase and amylase preparations in saccharofication of insoluble substrates containing starch have been studied.

Key words: glucoamylase, amylase, screening, carbon sources, hydrolysis of insoluble substrates.
