The present study deals with the optimization of substrate and fermentation conditions for the production of both pectinase and cellulase by Aspergillus niger NCIM 548 under same fermentation conditions in submerged fermentation (SmF) and solid state fementation (SSF) using a central composite face centered design of response surface methodology (RSM). As per statistical design, the optimum conditions for maximum production of pectinase (1.64 U/mL in SmF and 179.83 U/g in SSF) and cellulase (0.36 U/mL in SmF and 10.81 U/g in SSF) were, time 126 h, pH 4.6, and carbon source concentration 65 g/L in SmF and were time 156 h, pH 4.80, and moisture content 65% in SSF. The response surface modeling was applied effectively to optimize the production of both pectinase and cellulase by A. niger under same fermentation conditions to make the process cost-effective in both submerged and solid state fermentation using agro industrial wastes as substrate.
