A amylase producing bacteria were isolated from tofu residue and identified as Bacillus sp. according to the morphological and biochemical properties, which were named Bacillus sp. GM7330 and Bacillus sp. GM7312. The cultural condition for the production of amylase was showed on 5% tofu residue added 3% glucose and 0.15% yeast extract. And incubated during 72 hrs at 30℃, Bacillus sp. GM7330 and Bacillus sp. GM7312 were producing amylase of 488 units and 341 units.
