ABSTRACT:
The present invention describes a simple and inexpensive purification method for acid-stable fungal alpha-amylase wherein the alpha-amylase is obtained without significant loss of enzyme activity. The purified acid-stable alpha-amylase which is obtained is substantially free from glucoamylase. The method for obtaining an acid-stable alpha-amylase comprises the steps of
