Cyclodextrin glycosyltransferase를 생산하는 호알칼리성 Bacillus속 미생물
Isolation and Characterization of Cyclodextrin Glycosyl Transferase Producing Alkalophilic Bacillus sp.
초록
Cyclodextrin(CD) 생성효소(CGTase)를 생산하는 미생물을 토양으로부터 알칼리 (pH10.3) 조건하에서 1주 분리하여 동정한 결과, pH 7.5~ll.0까지 생육하는 절대 호알칼리성 Bacillus sp.이었다. 분리균주가 생산하는 효소는 전분으로부터
A strain of alkalophilic Bacillus sp. YC-335 has been isolated from soil. The strain was capable of producing large amount of cyclodextrin glycosyl transferase (CGTase) in the culture broth. The preferable medium composition has been determined to be as follows : 1.5% soluble starch, 5% corn steep liquor, 0.1%
