An extracellular glucoamylase enzyme was isolated from Aspergillus niger Z10 natural isolate in a liquid Czapek Dox medium which contained soluble starch (2%) as the sole carbon source. The molecular weight of the enzyme was found to be about 100.000 Daltons through Starch-SDS Polyacrylamide Gel Electrophoresis. The optimal pH range of the enzyme was found to be 4.5-5.5 and it was determined that the thermal stability of this enzyme is quite high.
Aspergillus niger, Glucoamylase.
