Process optimization of glucoamylase production by aspergillus niger using low cost bitter cassava (manihot esculenta)

The effect of process parameters on glucoamylase production from bitter cassava by Aspergillus niger was studied using response surface methodology (RSM). Face centered central composite design (FCCCD) was selected to evaluate the optimum levels of the three param...
