土默川平原葡萄酒相关酵母的分离与鉴定

Separation and Identification of Wine Related Yeasts Isolated from Tumochuan Plain

本研究利用WL培养基对内蒙古土默川平原酿酒葡萄中的酵母菌种进行了鉴定;同时,考察了不同发酵时期,葡萄汁中酵母菌种的分布情况。结果表明,该地区葡萄酒相关酵母分属于5个属的6个酵母菌种,分别为葡萄汁有孢汉逊酵母(Hanseniaspora uvarum)、酿酒酵母(Saccharomyces cerevisiae)、东方伊萨酵母(Issatchenkia orientalis)、克鲁维毕赤酵母(Pichia kluyveri)、异常毕赤酵母(Pichia anomala)及星形假丝酵母(Candida stellata);在不同发酵时期,葡萄汁中酵母菌种的分布情况不同。实验表明,该地区酿酒葡萄中的酵母菌种具有多样性。

In this study, wine related yeasts were isolated from Tumochuan plain of Inner Mongolia and identified using WL medium; at the same time, in various fermentation periods of grape juice, the yeast distribution was also explored. The results showed that there were six speeies of yeast, which were Hanseniaspora uvarum, Saceharomyces eerevisiae, Issatehenkia orientatis, Pichia kluyveri, Pichia anomala and Candida stellata separately, and could be sorted into five genuses. This study indicates that the wine related yeasts are diversity this area.
