摘要：
Soyhull a lignocellulosic material produced in large amounts during soybean processing, was utilized for cellulase production through solid-state fermentation. Of five known fungi, Phanerochaete chrysosporium gave maximum yields of the enzyme. Optimum pH of the substrate and temperature of incubation were 4 . 0 and 25 degrees C. Under optimized conditions, the addition of urea at 2% (w/w) could enhance the enzyme yields to 74 . 8 IU/gram dry solids (CMCase) and 29 . 1 IU/gds (FPase) from the initial values of 27 . 5 IU/gds (CMCase) and 12 . 2 IU/gds (FPase). The optimum size of the inoculum was 1 . 0 x 10(4) viable spores/gds.
