摘　　要：以L-苯丙氨酸为起始原料,酿酒酵母为生物催化剂,经过艾氏途径,得到β-苯乙醇,历时3个月完成50 L发酵罐中试研究,L-苯丙氨酸转化率最高达到80.3%,发酵液β-苯乙醇含量多数可以达到3 g/L以上,原料和产物的含量测定由气相色谱-质谱联用仪(GC-MS)完成。β-Phenylethanol was synthesized from L-phenylalanine by Ehrlich-way with a bioeatalyst of saccharomyces cerevisiae. Enlarge pilot study was carried out at a fermenter-tank of 50 L for 3 months, the highest conversion rate of L-phenylalanine was reached 80.3 % , most of the content of fermentation broth of β-phenylethanol was reached more than 3 g/L, the content of the raw materials and products was determined by GC-MS.
