Reductive conversion of geraniol to citronellol is adopted as a model reaction, and several factors in the reaction are discussed using gas chromatography method. The influence of n-hexane and butyl acetate, as organic solvents, on biocompatibility was studied; the influence of methanol, ethanol, glycol, n-butanol and 1-hexanol, as energy substance, on the transformation efficiency was compared, respectively; the catalysis capabilities of Baker's yeast, XST-KO yeast, LP yeast, alcohol yeast, dry yeast, Saccharomyces cerevisiae, Angel yeast and Meishan yeast were discussed. It has been proved that biocompatibility of n-hexane are much better than that of butyl acetate, and the hexane has been demonstrated the most effective in terms of the influence on biotransformation, Baker's yeast has shown the highest tranformation efficiency among the eight yeast strains.

以香叶醇转化为香茅醇作为模型反应，通过气相色谱法进行定性和定量分析研究了影响该有机相生物转化反应的几个基本因素，考察了两种有机溶剂正己烷和乙酸丁酯对生物相容性的影响，选用甲醇、乙醇、乙二醇、正丁醇和l-己醇分别作为能量物质进行实验，比较其对转化的影响并探讨了Baker's酵母、XST-KO酵母、LP酵母、酒精酵母、假丝酵母、干酵母、安琪酵母和梅山酵母八种不同酵母作为生物催化剂对模型反应的催化能力，结果表明，正己烷作为有机溶剂，其生物相容性明显好于乙酸丁酯，更加有利于该生物转化反应进行；乙二醇作为能量物质，该模型反应转化率最高；而 Baker's酵母作为生物催化剂，对该模型反应的催化能力最强，最适合作为该模型反应的催化剂。
