PREPARATION METHOD OF AMYLASE PRODUCING MALTOTETRAOSE

摘要

This invention provides the method of preparing maltotetrose forming amylase. KFCC-10846 of streptomyces species is isolated from compost, and cultivated in an aerobic condition, i.e. the fermented culture medium mainly composed of cationic starch and oxidized starch. In this invention, the condensed maltotetrose forming amylase is produced by inexpensive carbon provider, i.e. the starch.
