摘要
[目的]比较不同酿酒酵母菌利用荔枝渣产酒精发酵性能,筛选出适合在荔枝渣培养基中发酵的最佳菌种。[方法]研究了5株酿酒酵母菌在荔枝渣培养基中的生长情况,测定了其在荔枝渣培养基中的失重量、产酒精能力和残糖含量。[结果]在最适生长温度为36℃,pH值为3.5的条件下,安琪耐高温高活性酿酒酵母发酵产酒精能力强。[结论]安琪耐高温高活性酿酒酵母在该条件下发酵综合性能最好。
[Objective]The aim was to select the excellent strain which performed powerful fermentation capability in litch residue substrate by comparison the fermentation performances of the five Saccharomyces cerevisiae.[Method]The growth performances in the litch residue substrate of five Saccharomyces cerevisiae were studied,the weight loss,ethanol production ability and residual sugar content of the five strains were determined.[Result]The results showed that the Angel Super Yeast had the powerful fermentation capability in litch residue substrate under the optimal growth temperature 36 ℃ and pH 3.5.[Conclusion]The Angel Super Yeast had the best overall fermentation capability for the suitable conditions.
