| 摘 要： | 利用3,5-二硝基水杨酸（DNS）法和硫化氢检测管检测法分析了高／低产硫化氢酿酒酵母菌株的发酵特性及其硫化氢产生特性。结果显示：高／低产硫化氢酿酒酵母茵株在发酵过程中的硫化氢产率变化趋势同为“双峰”趋势,且发酵前期峰值出现时间相同;高／低产硫化氢酿酒酵母在发酵速率和硫化氢产生比率上存在一定差异,且不同菌株的发酵速率与硫化氢产生比率之间没有必然联系。

| Abstract: | The characteristics of the fermentation and H2S formation of S.cerevisiae strains with high/low H2S yield rate were analyzed by DNS method and H2S detector tube.The results indicated that the change trend of H2S yield rate presented double peaks in both S.cerevisiae strains and peak value appearance time in prior fermentation period was almost the same,however,there was some difference in fermentation rate and H2S formation rate for the two kinds of S.cerevisiae strains and there was no necessary correlations between the fermentation rate and H2S formation rate. |
