产地葡萄酒优良酵母菌株的筛选及鉴定
Screening and Identification of Quality Yeast Strains in Grape Wine Production Area
【摘要】 从山东、甘肃、宁夏、陕西、新疆酿酒葡萄产区采集的99份葡萄果粒中分离到酵母258株,通过抗性和发酵特性评价,筛选出3株发酵性能优良的菌株。经菌落特征、细胞形态、生理生化特性鉴定,结合26S rDNA D1/D2序列,菌株ZYFJQ和QLMLZ2被鉴定为酿酒酵母,菌株ZYY73-2被鉴定为葡萄酒有孢汉逊氏酵母。
【Abstract】 258 yeast strains were isolated from the surface of 99 grape samples collected from grape wine production area including Shandong,Gansu,Shanxi,Ningxia and Xinjiang.3 quality yeast strains of excellent fermenting performance were screened out by the evaluation of their tolerance and fermenting properties.Strains ZYFJQ and QLMLZ were identified as Saccharomyces cerevisiae and strain ZYY73-2 identified as Hanseniaspora uvarum by the analysis of their morphological and physiological characteristics and their 26S rDNA D1/D2 sequence.
