Nutrient effects on production of cellulolytic enzymes by Aspergillus niger

  title={Nutrient effects on production of cellulolytic enzymes by Aspergillus niger},
  author={Golla Narasimha and Buddolla Viswanath and S. Chandra and Rajasekhar Reddy},
The production of cellulase (filter paper activity, endoglucanase and β-glucosidase) by Aspergillus niger on three media in liquid shake culture was compared. The culture filtrate of this organism exhibited relatively highest activity of all three enzymes and extracellular protein content at 7-day interval during the course of its growth on Czapek-Dox medium supplemented with 1.0% (w/v) cellulose. Urea as a nitrogen source and pH 5.0 were found to be optimal for growth and cellulase production… CONTINUE READING
