that biocatalytic hydrolysis of various esters using Baker’s yeast proceeds efficiently under neutral conditions without sucrose. Hydrolysis of ethyl, methyl, propyl, isopropyl, benzyl, allyl, prenyl, and vinyl esters of 3-phenylpropanoic acid using Baker’s yeast gave easily 3-phenylpropanoic acid in 52–86% yields. In contrast, Baker’s yeast did not hydrolyze the rigid structural esters such as cinnamyl
我们发现使用贝克酵母的各种酯的生物催化水解在没有蔗糖的中性条件下有效进行。使用贝克酵母水解 3-苯基丙酸的乙基、甲基、丙基、异丙基、苄基、烯丙基、异戊二烯基和乙烯基酯,很容易以 52-86% 的收率得到 3-苯基丙酸。相比之下,贝克酵母不水解刚性结构酯,如肉桂酯和 3-苯基丙酸苯酯。然后,贝克酵母水解各种 3-芳基丙酸、4-苯基丁酸和脂肪酸的乙酯,以 29-85% 的产率提供相应的酸。
