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...

A differential response in the production of enzyme activities was observed. Glucose (0.7%) acted as catabolite repressor for all the enzymes at a(w) = 1 and at a(w) = 0.975 for pectinesterase, pectinlyase and protease. For polygalacturonase at a(w) = 0.975 a synergistic stimulating effect was observed. By depressing a(w) a pectinase complex containing mainly pectinlyase and polyglalacturonase could be obtained.
