Abstract
Polyporus ostreiformis produced Mn peroxidase, acid protease, cx-amyla se, and lignin peroxidase, with maximum activities of 40, 8,300, and 4 ,200 U liter(-1) and 50 nkat liter(-1), respectively, in nitrogen-limi ted liquid media. The fungus removed only 18.6% lignin from rice straw in 3 weeks but effected 99% decolorization of Congo red dye in 9 days .
