Objective] This study was conducted to further explore the diversity of Saccharomyces cerevisiae_from Chateau Changyu Moser XV and realize better de-velopment and utilization of Saccharomyces cerevisiae resources. [Method] ln this study, the wine grape regions of Chateau Changyu Moser XV were taken as the research object. The Saccharomycetes_in the soil was isolated, screened and ob-served in the natural fermentation process of grape berry epidermis and the fruit. The 32 Saccharomycetes strains were preliminarily classified based on WL nutrient agar, and 26S rDNA D1/D2 sequence analysis was conducted. [Result] Total y, 4 kinds of Saccharomycetes were identified in this study, including Pichia kluyveri, Hanseniaspora uvarum, Saccharomyces cerevisiae_and Cryptococcus magnus. [Con-clusion] The main species of Saccharomycetes in the wine grape region of Chateau Changyu Moser XV were preliminarily determined, which provides theoretical basis and research basis for the brewing of wine with special characteristics.
为进一步探究宁夏贺兰山东麓酿酒葡萄酵母菌的多样性,更好开发利用葡萄产区酵母菌资源。从宁夏贺兰山东麓的西夏王陵、红寺堡、玉泉营、青铜峡、张裕十五世酒庄地区的葡萄园土壤、葡萄浆果表皮以及葡萄自然发酵过程中进行酵母菌的分离筛选,对得到的122株酵母菌株运用WL营养琼脂培养基进行初步分类,同时结合26S r DNA D1/D2区序列分析。共鉴定出克鲁维毕赤酵母(Pichia kluyveri)、美极梅奇酵母(Metschnikowia pulcherrima)、葡萄汁有孢汉逊酵母(Hanseniaspora uvarum)、酿酒酵母(Saccharomyces cerevisiae)、大隐球酵母(Cryptococcus magnus)共5种酵母菌。进而初步确定宁夏贺兰山东麓酿酒葡萄产区酵母菌的主要种类,为地方特色葡萄酒酵母菌的筛选和选育提供理论基础和研究依据。
