Combined effect of water activity depression and glucose addition on pectinases and protease production by Aspergillus niger
The combined effect of depressed water activity (a(w)) and glucose addition on the production of extracellular pectinases and protease by Aspergillus niger 148 was studied. A differential response in the production of enzyme activities was observed. Glucose (0.7%) acted as catabolite repressor for a...
