The rate of inhib ition of treatment iv - vi was higher than treatment i - iii . it is suggested that the three biotransformation enzymes may be directly or indirectly affected by the tested chemicals 三哇磷处理对肝脏酷酶活性在供试浓度范围和时间内，均有抑制作用， 96h时的抑制率在54 . 4一62 ， 5 %之间。

As to the solvent , hexane and butvul acetate is discussed and former is more suitable for biotransformation . among seven kinds of energy source : menthok alcohok glycok glycerou 1 - hexanok butyl alcohol octyl alcohol , glycol is selected as energy source , so hexane - glycol is used as reaction system 从生物相容性和有利于转化的角度对两种溶剂，正己烷和乙酸丁酯进行了比较，确定了正己烷?忆二醇为该模型反应的溶剂体系。

Study of " ph memory " and activity water ( aw ) in processing of immobilization indicates that former factor has much effect on transformation and the latter just has little effect . permeabilization treating of baker ' s cell with alcohol and ultrasonic leads to lower transformation rate , which illustrates that permeabilization procedure has negative role on biotransformation with whole cell as biocatalyst in organic solvent . in simple dynamics research amount of biocatalysu concentration of substrate and reaction course are considered and all of them have remarkable effect on transformation Ph记忆、水活度及通透性处理的实验结果表明， ph记忆对转化有明显的影响，水活度对模型反应的影响不大；作为完整细胞生物催化，细胞的通透性可能是传质阻力的重要组成部分，利用不同浓度的乙醇和超声波对细胞进行处理，结果表明，在有机相完整细胞生物催化中，通透性处理对转化产生的是负面影响。

Biotransformation in organic solvent is an attractived field in nowadays . compared with isolated enzyme whole cell is not used broadly as biocatalyst . in this research the cells of baker ' s yeast is adopted to mediated a model reaction in organic solvent , in which geraniol is converted to citronellol reductively 有机相生物转化是当前生物技术中一个具有理论研究意义和应用价值的领域，目前该领域的研究大多集中在利用分离的酶进行生物催化，利用微生物完整细胞进行的研究比较少。
