Abstract
Three Streptomyces isolates (A2, A5 and RB20) were collected from the Department of Microbiology, University of Chittagong, Bangladesh. Among them isolate A5 exhibited highest amylase production at 37°C temperature, medium pH 7.0 and 96 hrs of incubation period. 1.5% carbon (starch) and 1% nitrogen (yeast extract) was found to induce amylase production by the isolate Streptomyces albolongus (A5). Maximum glucoamylase activity was observed at 50°C temperature for 90 minutes and pH 7.0 along with 1% soluble starch as substrate concentration during enzyme substrate reaction.
