HETEROLOGOUS EXPRESSION OF AN ASPERGILLUS KAWACHI ACID-STABLE ALPHA AMYLASE AND APPLICATIONS IN GRANULAR STARCH HYDROLYSIS |
摘要 |
The present invention relates to a granular starch hydrolyzing enzyme composition comprising an acid stable alpha amylase (asAA) having granular starch hydrolyzing activity. The invention also relates to a one-step method for producing an alcohol which comprises contacting a granular starch substrate with an acid- stable alpha amylase (asAA) having granular starch hydrolyzing (GSH) activity and a glucoamylase (GA) in a fermentation step which also comprises ethanologenic microorganisms at a temperature of 25 - 40‹C to obtain a fermentation broth having 5 to 20% ethanol. ® KIPO & WIPO 2007 |
