The extracellular plant cell wall degrading enzymes of Phymatotrichum omnivorum and the effect of different carbon sources on the production of these enzymes were investigated. Cellobiohydrolase, endoglucanase and xylanase activities were detected in fluids collected from cultures containing sodium carboxymethyl cellulose (CMC) or xylan as carbon sources and enzyme inducers. The highest activities of cellobiohydrolase and xylanase were measured in fluids collected from cultures containing xylan. Results of this study indicate that P. omnivorum constitutively produces small amounts of endoglucanase.
