Production of Cellulases by Aspergillus Heteromorphus from Wheat Straw under Submerged Fermentation

Authors: Namita Singh, Anita Singh, Narsi R. Bishnoi


To investigate the production of cellulases from Aspergillus heteromorphus, submerged fermentation was performed using wheat straw as substrate. Optimization of saccharification conditions like pH, temperature and time were studied. Highest reducing sugar was released on 5th day at 5 pH, 30° C temperature. When A. heteromorphous was grown on wheat straw in submerged fermentation after 5 days incubation at 30 ° C, 3.2 IU/ml and 83 IU/ml, filter paper activity and CMCase activity respectively.

Keywords: submerged fermentation, wheat straw, Aspergillus heteromorphus, Production of Cellulases
