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.
