Abstract

Alpha-amylase production by solid formentation wit11 two strains of bacteria are Bacillus subtilis Bacillus sp. NTU-900. 5 kinds of carbon source, such as wheat bran, rough rice bran, fine rlce bran, cassava and sorghum bran were use. Bacillus sp. NTU-900 is the best for :llpi~a-amylase production in ail carbon source studied. The optimum condition for this strain arc the ratio be~ween rough rice bran to fine rice bran 40 to 30% mixed with water pH 7.0 with the ratio between medium to water 1 to 0.5 and add Na2HP04. 12H,O for growth factor and after incubation at 3 f fo~r 72 h r can ga alpha-amylase activity about 400 unit per gram.
