| Abstract: | A strain of Aspergillus terreus 4 was found to show extracellular amylolytic activity and the amylase was identified as glucoamylase enzyme. The optimum temperature for the enzyme activity was 60% and it was stable at this temperature for 1 h. The enzyme was optimally active at pH 5.0 and stable between pH 3.0-8.0. Km values of glucoamylase for soluble starch, amylose and amylopectin were 5.9 mg/ml, 4.8 mg/ml and 2.6 mg/ml respectively. |
