Cellulase, xyloglucanase, and xylanase activities of Aspergillus niger (An), Trichoderma reesei (Tr), Myceliophthora thermophila ATCC 42464 (Mt), and Myceliophthora heterothallica CBS 202.75 and CBS 663.74 after growth on wheat straw pretreated with 20% HCl. The activities are measured by the amount of reduced sugar released and are given in nmol or μmol reduced sugar per min per mg of total protein. The averages and standard deviations represent two independent cultivations and at least four technical replicates.
