Method for production of alpha-amylase in recombinant Bacillus

摘要

Disclosed is a novel recombinant Bacillus bacterial strain constructed by genetic engineering which has high productivity of aipha-amylase. The Bacillus strain comprises an alpha-amylase gene inserted in the Bacillus chromosome under transcriptional control of a phage promoter. An efficient process for the rapid production of large amounts of alpha-amylase is also disclosed.
