Abstract
This invention contemplates a novel process for the preparation of solution stable alpha-amylase obtained from Bacillus licheniformis, and to the high potency liquid enzyme product prepared by this process. Typically, the enzyme-containing solution from a fermentation is concentrated and starch is added to the concentrate. Alternatively, a precipitation agent such as salt is added to the solution, and a cake containing the enzyme precipitates. The cake is then contacted with an aqueous solution containing starch to extract the enzyme out of the cake to provide a stable liquid enzyme product.
