Production of cellulase enzyme by mutant fungal strain Aspergillus niger in submerged fermentation

M.Reddi Pradeep, G.Narasimha

Production of enzymes is a growing field of biotechnology especially related to industrially important enzymes. The present studywas carried out to investigate the production of cellulase enzyme from UV mutated Aspergillus niger grown on rice bran under submerged fermentation. The fungal strain Aspergillus niger was subjected to UV irradiation and the successive mutants showed enhanced cellulase production. Particularly, the mutant fungal strain Aspergillus niger GNUV3 was efficient and the activities of carboxy methyl cellulase, filter paperase and â-glucosidase were improved by 4.7, 4.4 and 3.8 – fold, respectively when compared to the wild type strain.
