✦ Synopsis

More than 600 micromycetesrepresentatives of different genera have been investigated for their ability t o produce exogenous cellulases. Most of the investigated cultures were found to produce these enzymes, 24 cultures being thermophilic, and 16 thermotolerant. Cellulase or its derivatives proved to be the most favourable carbon source for cellulase secretion. None of the thermophilic cultures studied manifested the ability of exogenous exoglucanase biosynthesis. Using UV-rays as mutagen, a mutant strain A . terreus T-49 has been obtained being characterized by an increased endo-glucanase and cellobiase activity, as compared t o the initial strains. The cellulase preparations of thermophilic micromycetes contain one cellulasic component: endo-glucannse, or two : endo-glucanase and cellobiase.
