几株酒精酵母的发酵性能比较

Comparison of the Fermentation Performance of Several Strains of Alcohol Yeast

酵母菌种的好坏直接影响产品质量、设备利用率和产品产量,从而影响企业的经济效益。对1308菌株、1300菌株、安琪超酒酵母、奥特奇酵母产酒精的发酵、耐乙酸、耐乳酸、耐受酒精能力、耐受温度、耐渗透压、耐pH进行了发酵实验比较。结果表明,1308菌株、1300菌株、安琪超酒酵母、奥特奇酵母各有优缺点;菌株1308及安琪超酒酵母生产性能良好。(孙悟)

Fermentation microbial species would influence directly product quality, the utilization rate of the equipments, and the product output, which would further influence the economic benefits of the enterprises. Through the comparison of the fermentation performance （including acetic acid resistant capacity, lactic acid resistant capacity, alcohol resistant capacity, temperature resistant capacity, osmotic pressure resistant capacity, and pH resistant capacity） of strain 1308, strain 1300, Angel super yeast and American yeast, it was concluded that each strain had its own advantages and disadvantages and strain 1308 and Angel super yeast had satisfactory production performance.
