[Search for micromycetes--producers extracellular catalase and study of conditions of its synthesis].
Production of extracellular catalase by microscopic mycelial fungi (255 strains) belonging to different taxonomic groups was studied. Producers of extracellular catalase were found among fungi of the genera Penicillium, Talaromyces and Aspergillus. Strains of the genus Penicillium were the most active producers. The formation of catalase depended on the initial pH, carbon and nitrogen sources and their ratio, and the content of microelements in the medium. The yield of extracellular catalase produced by the strains selected (P. chrysogenum, P. funiculosum, P. pinophilum, and P. minioluteum) was not less than 400-1400 U per ml culture liquid.
