Microorganisms producing high-activity active -galactosidase and method for producing high-activity active -galactosidase using the same

摘要

The present invention relates to a novel mutant capable of producing -galactosidase having a high transactivation activity and a method for producing -galactosidase using the same.;The strain of the present invention is a strain of Bacillus sp. Strain A1, which is a microorganism producing a -galactosidase, is a bacillus strain which produces a -galactosidase with high transactivation activity, This strain is cultivated in a fermentation medium to accumulate -galactosidase and recover the enzyme from the culture medium to produce a high-activity, metabolite repressor (Bacillus sp.) MWG 4442 (KFCC-10855) Cataboliter repression can produce -galactosidase to some extent.
