a mutant of its parant strain obtained by using compound mutagenizatioc with UV irradiation and NTG treatment
produces an active α amylase when it was cultured in the liquid medium containing fowl feather powder or swine blood meal as the main nitrogen source. The present paper deals with the cultural conditions for α-amylase production by the organism and some properties of the enzyme.The essential results obtained from our present study are summarized as.follows:The optimal cultural temperature for enzyme formation was 30℃
and the most suitable havesting time was 48 hours after incubation.The enzyme was quite stable around pH 5 and at 40℃.The enzyme was well protected from heat denaturation by Ca
