Keyword:  Penicillium expansum TS414生物柴油固定化酯交换反应;
Abstract: 为了促进酶法生产生物柴油工艺在工业上的应用,对固定化Penicillium expansum TS414脂肪酶进行了相关研究.结果表明,固定化Penicillium expansumTS414脂肪酶具有最佳的酯交换性能.在固定化酶量为20%、乙醇/大豆油摩尔比为3:1、水分含量为4%的酯交换条件下,反应8h,反应转化率可达92.6%.此外,固定化酶具有良好的操作稳定性-使用8批次后,酶活仅损失17.3%.P.expansum TS414固定化脂肪酶的酯交换性能较好、价格较为低廉,可成为合成生物柴油的良好催化剂.
