Acid-stable alpha amylases having granular starch hydrolyzing activity and enzyme compositions

摘要

The present invention relates to an acid-stable alpha amylase (asAA) derived from a strain of Aspergillus kawachi, which has granular starch hydrolyzing (GSH) activity, the heterologous expression of the asAA having GSH activity in filamentous fungal host cells and enzyme compositions including the same which optionally include glucoamylase.
