| 摘 要： | 从陕西糯米稠酒小曲中分离得到11株酵母菌,经过产气性能实验、TTC显色实验,初筛得到4株酵母,再通过发酵实验复筛,最终筛选出1株高产酒精酵母Y11。该菌株在28℃条件下,静止发酵96h后酒精体积分数可达10.5。通过形态分析和生理生化实验鉴定为酵母属(Saccharomyces)的酿酒酵母(Saccharomyces cerevisiae)。

| Abstract: | Four strains of yeasts were selected and purified from liqueur yeast used in the production of Shaanxi glutinous rice wine. After primary selecting in terms of ability of gas producing and TTC coloration test,4 yeasts were obtained for further ferment experiment. Results of experiments showed that yeast Y11 is the perfect strains for high alcohol yield producing. It was identified as Saccharomyces cerevisiae through morphological analysis and physiobiochemical experiment. Under the condition that the temper... |
