【摘要】 为了获取具有较强降解苹果酸能力的葡萄酒酵母,实验以酿酒酵母和粟酒裂殖酵母为出发菌株,进行了原生质体融合研究,并通过利用双亲特有的遗传标记进行了有效的融合子检出工作,最终获得一株降苹果酸能力和发酵能力均较强的双亲融合子,该方法简单易行,加快了双亲融合子检出过程。更多还原

【Abstract】 In order to obtain the wine yeast strain with high ability of malic acid-degradation,some studies relating to protoplast fusion and fusant selection have been done.In these studies,we used Saccharomyces cerevisiae and Schizosaccharomyces pombe as primary strains,and found their some proper genetic markers for fusant selection.Finally,a fusant with good ability of fermentation and malic acid-degradation was obtained.The way to be used here is easy and feasible,it can quicken the course of fusant selection.更多还原
