high cellulase activity ( 16 to 17 iu/ml ) per unit volume of enzyme broth and high yields of cellulases were attributed to the growth of t. reesei on a hemicellulose fraction during its first phase and then on a cellulose fraction of wheat straw during its later phase for cellulase production , as well as to the close contact of hyphae with the substrate in solid-state fermentation .
