Abstract
In order to produce transglucosylated steviosides continuously, some types of bioreactors were investigated with cyclodextrin glucanotransferase immobilized on a high porous anion exchange resin, Diaion HPA75. Among the bioreactors, the packed-bed reactor (PBR) showed the highest specific productivity. The effect of linear velocity in a PBR on the stevioside conversion was not significant in the range of
고정화 CGTase를 이용하여 당전이 스테비오사이드를 연속적으로 제조하기 위하여 몇가지 생물반응기의 적용가능성을 조사하였다. 연속형 반응기로는 packed-bed reactor(PBR)가 적합하였다. 이때 specific productivity는 0.4 g/hr-g immobilized enzyme으로 회분식반응기의 50% 정도이나 연속생산이 가능한 장점이 있었다. PBR의 운전조건이고
