The present study was concerned with the production of various enzymes such as amylase, cellulase, xylanase, avicelase and FPase by Aspergillus niger in submerged fermentation at 30 degree C for 72h of fermentation period using Vogel's media and sugarcane bagasse as a substrate. Different concentrations of 2-mercaptoethanol were evaluated on the production of enzymes by Aspergillus niger. It was observed that addition of 2-mercaptoethanol to the fermentation medium greatly inhibited the xylanase and alpha-amylase production by Aspergillus niger but addition of 2011 concentration of 2-mercaptoethanol to the fermentation medium favored the production of CMCase, FPase and total protein.
