Novel enzyme product and its use in the saccharification of starch

摘要

A novel acid amylase is provided, isolated from amyloglucosidase, having a greater thermostability than amyloglucosidase and a comparable pH-optimum. This acid amylase can be used advantageously in conjunction with amyloglucosidase and optionally with an acid pullulanase in the saccharification of starch and starch hydrolysates. Also, a novel enzyme product is provided comprising acid amylase having alpha -1,4-glucosidic bond splitting activity and amyloglucosidase and optionally acid pullulanase.
