Abstract
A bacterial strain, producing extracellular inulin fructotransferase which converts inulin into di-D-fructofuranose 1,2':2,3' dianhydride(DFA III), was isolated from soil and presumed as Bacillus sp.. The highest production of the enzyme was obtained by using medium containing Jerusalem artichoke extract as carbon source, peptone as organic nitrogen source, and
Inulin을 가수분해하여 di-D-fructofuranose dianhydride(DFA)를 생성하는 inulin frucroransferase를 분비하는 균주를 토양으로부터 분리하였으며, Bacillus sp로 동정하였다. 본 효소에 의하여 생성되는 DFA는 TLC 와 HPLC로 분석한 결과, fructose 두 분자가
