摘要：
Lipase can mediate the chemo-enzymatic epoxidation of alkenes with the presence of free carboxylic acid and hydrogen peroxide. Four novel lipases with the abilities of chemo-enzymatic epoxidation were mined from the gene database. Lipase TiL originated from Tilletia indica was identified with significant activity on formation of methyl epoxystearate from methyl oleate. n-Heptanoic acid was determined as the optimal carboxylic acid substrate of TiL. Methyl oleate and alpha-pinene were efficiently converted to corresponding epoxy compound in micro-aqueous media and aqueous-organic biphase, respectively. A preparative scale chemo-enzymatic transformation of alpha-pinene was conduct using the optimized reaction condition, with 30 % yield of alpha-pinene oxide obtained.
