摘要： Variants of Bacillus sp. TS-23 strain alpha-amylases exhibit improved enzymatic performance, including increased themostability, reduced calcium dependence, increased washing/cleaning performance, and baking ability. Compositions comprising these variants are useful in methods of starch processing, starch liquefaction, fermatation, starch saccharification, cleaning, laundrying, textile desizing, baking, and biofilm removal.
