ABSTRACT:

P. purpurogenum isolated from decaying wood sample in our laboratory produces comparable amount of beta-glucosidase. The intracellular and extracellular enzymes reached to the peak after 4 and 8 days respectively. Germinating spores of this strain were subjected to mutagenesis with U.V and NTG (3-nitro, 5 methyl guanidine). After mutagenesis, both the treatments have shown induction in beta-glucosidase production to significant level.
