摘　　要：在酒精生产中,酵母的发酵是影响酒精产量与质量的重要因素。在现有的技术条件下,通过诱变育种、细胞杂交等生物化学技术,可以得到耐高温、高产量的酒精酵母菌株。在这一前提下,结合高密度发酵所需的必要条件,对高密度发酵制取酒精的工艺流程进行了优化,并重点介绍了真空抽提、二氧化碳气提、膜渗透蒸发、液体萃取等方面的技术要点。In the production of alcohol,the fermentation of yeast is an important factor affecting the yield and quality of alcohol.Under the existing technical conditions,through biochemical techniques such as mutagenesis breeding,cell hybridization,etc.,high-temperature tolerance and high-yield saccharomyces cerevisiae can be obtained.Under this premise,combining the necessary conditions for high density fermentation,this article introduces the optimization of the alcohol production process by high density fermentation,focusing on the key technique points on vacuum extraction,carbon dioxide stripping,film pervaporation,liquid extraction,etc.
