摘要:

运用Interdelta PCR 指纹图谱分析技术,对从沙城产区龙眼葡萄相关的葡萄园土壤、酿酒设备和自然发酵过程中分离得到的54 株酿酒酵母(Saccharomyce cerevisiae)进行亚种水平的区分鉴定,研究不同酿酒酵母的分布和变化规律。结果表明:54 株酿酒酵母产生7 种指纹图谱,代表7 种不同的基因类型,基因型Ⅰ~Ⅶ分别占所分离菌株的31.5%、11.1%、7.4%、42.6%、3.7%、1.85% 和1.85%。自然发酵中后期有4 种基因类型的酵母菌,酿酒设备表面3 种,葡萄园土壤中2 种。通过聚类分析软件处理所得数据作出树形图,可直观地看出亚种第Ⅰ和第Ⅳ的亲缘关系最近,而第Ⅶ与其他亚种的亲缘关系最远。

Abstract:

Interdelta PCR fingerprinting technology was used to differentiate 54 Saccharomyce cerevisiae strains isolated from vineyard soil, brewing equipments and spontaneous fermentation process of Longan grape in Shacheng area. Results indicated that 7 genetic patterns were distinguished by Interdelta PCR fingerprinting. The genetic patterns I through VII accounted for 31.5%, 11.1%, 7.4%, 42.6%, 3.7%, 1.85% and 1.85%, respectively. The numbers of genotypes of yeasts isolated the late stage of spontaneous fermentation, the surface of brewing equipments and vineyard soil were 4, 3 and 2, respectively. Based on the cluster analysis tree, the genetic pattern I and IV had the closest genetic relationship, and the genetic pattern VII had the most far genetic relationship with others. The distribution and variation discipline of different Saccharomyce cerevisiae strains will provide a theoretical foundation for choosing excellent strains with their own favor characteristics.
