Cyclodextrin Production from Potato Starch with Bacillus stearothermophilus Cyclomaltodextrin Glucanotransferase
Bacillus stearothermophilus의 Cyclomaltodextrin Glucanotransferase를 이용한 감자전분으로부터의 Cyclodextrin 생산
Abstract
Simultaneous liquefaction and cyclodextrin (CD) production were conducted on potato starch using cyclomaltodextrin glucanotransferase (CGTase) from a mutant strain MNNG 8 of Bacillus stearothermophilus No. 239. A high concentration (30%) of potato starch was converted to cyc1o-dextrins (CDs) with 29% yield in the conditions of pH 6.0, temperature
Bacillus stearothermophilus No.239의 돌연변이주 MNNG 8이 생산하는 CGTase를 사용하여 감자전분을 동시 액화, cyclodextrin(CD) 생산을 하였다. 고농도(30)의 감자전분이 29의 수율로 CD로 전환 되었으며 그 때의 조건은 pH 6.0,
