摘　　要：研究了在2-苯乙醇发酵中提高发酵单位的方法—原位产物分离技术,通过对比不同溶剂的效果,确定了聚丙二醇1200为最佳溶剂,最终有机相中2-苯乙醇浓度最高达44.3 g/L,总的2-苯乙醇浓度达到10.8 g/L,比单水相发酵的苯乙醇浓度5 g/L提高了2倍,突破了制约2-苯乙醇发酵的瓶颈问题,推动了该产品的产业化进展。The study analyzes one of the methods to increase the fermentation unit in 2-phenylethanol fermentation,in situ product removal technology.Based on the comparison of the effects of different solvents,polyethylene glycol 1200 is determined to be the best solvents.The final concentration of 2-phenylethanol in the organic phase is up to 44.3 g/L,the total concentration of 2-phenylethanol is 10.8g/L,which is 2 times up the result of concentration of 2-phenylethanol 5 g/L.It has broken through the problem in restricting the fermentation of 2-phenyl ethanol,and promoted the industrialization of the product.
