[Cellulolytic activity of Fenellia flavipes and Fusarium oxysporum strains]

The production of cellulolytic enzymes by Fenellia flavipes and Fusarium oxysporum strains in submerged culture with plant residues as carbon source was studied. It was established that the majority of studied strains was able to hydrolyze the filter paper, husk of sunflower seeds, wheat straw and corn stalks. The ability to synthesize enzymes depended on the strain of microscopic fungi, type of substrate and duration of cultivation. As a result two fungal strains were selected: F. flavipes 655 with maximum of cellulolytic activity 2 U/ml in the medium with wheat straw and 1.6 U/ml in the medium with corn stalks on the 4th day of cultivation and F. oxysporum 420 which synthesized 0.875 mg/ml of reducing sugars.
