Produced by submerged fed-batch pure culture fermentation of a genetically modified nonpathogenic and nontoxigenic strain of Bacillus licheniformis. The sequence of the alpha-amylase gene, originally derived from B. licheniformis, has been modified to confer thermostability on the enzyme. The B. licheniformis production strain was developed using a host strain derived from a nonpathogenic and nontoxigenic B. licheniformis ancestral strain.
