张裕摩塞尔十五世酒庄酿酒葡萄酵母菌分离筛选及鉴定

摘要

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.%[目的]为进一步探究张裕摩塞尔15世酒庄酿酒葡萄酵母菌的多样性，更好开发利用酒庄酵母菌资源。[方法]从张裕摩塞尔十五世酒庄的葡萄园土壤、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32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 rDNA D1/D2区序列分析。[结果]共鉴定出克鲁维毕赤酵母（Pichiakluyveri）、葡萄汁有孢汉逊酵母（Hanseniasporauvarum）、酿酒酵母（Saccharomyces cerevisiae）、大隐球酵母（Cryptococcus magnus）共4种酵母菌。[结论]初步确定张裕摩塞尔15世酒庄酿酒葡萄酵母菌的主要种类，为酿造具有酒庄特色葡萄酒提供理论基础和研究依据。
