The study involved the production of amylase from Aspergillus niger grown on yam peels in solid state fermentation. The process parameters: temperature, pH (initial) and incubation time were optimized for maximum amylase production using central composite design (CCD) of response surface methodology (RSM). Temperature was the most significant (p<0.05) parameter and the maximum interaction occurred between temperature and incubation time. The results of the study indicated that amylase is maximized (30.95 U/ml-min) at optimized levels of 49.53°C, 5.95 and 104 h for temperature, pH (initial) and incubation periods, respectively.
