Title:
NOVEL ACID- AND HEAT-RESISTANT alpha-AMYLASE, PROCESS FOR PRODUCING THE SAME, AND METHOD OF LIQUEFYING STARCH BY USING THE SAME
Document Type and Number:
WIPO Patent Application WO/1994/013792
Kind Code:
A1
Abstract:
A novel alpha-amylase excellent in acid and heat resistances, which is produced by a microorganism of the genus Bacillus licheniformis alpha and is capable of liquefying corn starch under an acidic condition of pH 4.0-5.5 at a temperature of 90-110 �C. Furthermore glucose can be obtained in a high yield by saccharifying corn starch with glycoamylase without adjusting the pH value.
