The various culture conditions of Trichoderma viride(ATCC 3454) and Phanerochaete chrysosporium(ATCC 26921) with glucose-pepton medium, Mandels medium, YMG medium for wood degradable enzyme were examined. Mycellium of the two species grew profusely on glucose-pepton medium. Maximum fungal growth was observed about 10days. But CMCase, Fpase, laccase activity in the culture medium with glucose-pepton was not detected. When grown in fermenter culture using Mandels medium, Trichoderma viride produced CMCase and Fpase. Its CMCase activity was 0.15 lU/ml and Fpase activity was 0.3 IU/ml within about 4-6days. Phanerochaete chrysosporium grown in a YMG medium gave the best enzyme activity when they were grown under stationary culture with an atmosphere of 100% oxygen. Levels of laccase activity of 3.0 mull were achieved in stationary culture under 100% oxygen. The enzyme condensation by ultrafiltration method caused a 2-fold(cellulase) and 6-fold(laccase) as compared to control activity.
