ABSTRACT
Aspergillus fumigatus Fresenius was isolated from goats rumen and exhibited highest amylase production at temperature 37°, medium pH 7.0 and 3 days of incubation period. Four percent starch as carbon source and 0.25% (NH4)2HPO4 as nitrogen source was found to induce amylase production by the isolate Aspergillus fumigatus. Maximum glucoamylase activity was achieved at 35° temperature and pH 7.0 along with 4% starch as substrate concentration during enzyme-substrate reaction.
