Patil 1 University Department of Biochemistry, L.I.T. Premises, Nagpur University, Nagpur - 440 033 (India) 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. https://www.biotech-asia.org/vol3no1/enhanced-beta-glucosidase-production-by-mutagenesis-in-penicillium-purpurogenum/ Beta-glucosidase; mutagenesis; Penicillium purpurogenum
