| 摘 要： | 高级醇是在酒精发酵过程中由酿酒酵母代谢产生，在酿酒酵母细胞质和线粒体中由基因编码相关的酶催化α-酮酸脱羧还原而成，是酒的重要香气成分，对酒的香气和口感有重要影响。该文综述了高级醇代谢的相关途径及部分关键基因及功能，以期深入分析了解高级醇并为通过分子生物学方式构建适用于工业生产的低产高级醇的酵母菌株提供理论参考。

| Abstract: | Higher alcohols are aroma components of alcoholic drinks and have important effects on the aroma and taste. They are produced by Saccharomyces cerevisiae during the process of alcoholic fermentation, and related enzymes encoded by genes in the cytoplasm and mitochondria of S. cerevisiae. α-keto acid is catalyzed into corresponding higher alcohols by the functions of decarboxylation and reduction. The related metabolic pathways, partial key genes and functions of higher alcohols were expounded, so as to deeply analyze higher alcohols and provide theoretical reference for strain with the low-yield higher alcohols, which was constructed by molecular biology and applied for industrial production. |

| Keywords: | Saccharomyces cerevisiae higher alcohols gene expression metabolic regulation |
