Laccase production byCyathus bulleri was lower in lignins and phenolic compounds as compared to malt extract medium (8 U/mL) which increased significantly on supplementing these compounds with malt extract. Of the different lignins and phenolic compounds, Reax, lignin and orcinol exhibited maximum laccase formation (12 and 68 U/mL, respectively) under static culture conditions, while sugars repressed it. Laccase activity inC. bulleri was higher under static than under shaking cultivation conditions. Moreover, agitation repressed laccase formation even in the presence of inducers.
