BETA-AMYLASE ENZYME PRODUCT, PREPARATION AND USE THEREOF

摘要

A novel beta -amylase enzyme product with improved thermostability and acid-stability is provided. The novel enzyme can be produced by cultivating a newly discovered microorganism Bacillus sp. (2l - 5l) belonging to the Bacillus acidopullulyticus complex, or by cultivating a host microorganism transformed with the gene coding for the novel enzyme, and may be used alone or in combination with a variety of conventional debranching enzymes in the production of high maltose syrups.
