【摘要】 筛选获得一株１，６－二磷酸果糖（ＦＤＰ）的高产酵母菌株，改变通透性后的酵母细胞，在发酵及固定化生产ＦＤＰ过程中发现Ｆｅ２＋和甘油能大量提高ＦＤＰ的积累。将戊二醛交联后的酵母细胞，用卡拉胶固定化后，装入酶反应柱，连续生产ＦＰＤ，柱反应可稳定在１０天以上，转化率维持在２０％以上。更多还原

【Abstract】 A strain of yeast has been selected for preparation of fructose-1,6-diphcophate(FDP).Continuous preparation of FDP was attempted by means of glutaraldehyde cross linked yeast cells immobilized by carrageenin in column reactor, the influence of velocity of substrate solution, pH,T,Fe2+ and glycerol on FDP accumulation was studied. The steady level of FDP production was maintained at least 10 days in column reactor.更多还原
