摘要
采用高通量测序技术对湖北宜昌当地传统米酒曲与广西玉林传统米酒曲中的微生物群落结构进行解析,获得了酒曲中主要微生物种属和占比。结果表明,广西米酒曲在物种丰富度以及群落多样性上均高于宜昌米酒曲;广西米酒曲中优势真菌属以根霉属(Rhizopus)、毛霉属(Mucor)、毕赤酵母属(Pichia)和假丝酵母属(Candida)为主,宜昌米酒曲中根霉属(Rhizopus)和毛霉属(Mucor)为优势菌属;在细菌属水平上,广西米酒曲以片球菌属(Pediococcus)、假单胞菌属(Pseudomonas)、魏斯氏属(Weissella)、乳杆菌属(Lactobacillus)为主,宜昌米酒曲优势菌属为假单胞菌属(Pseudomonas)和魏斯氏属(Weissella);ASV/OTU韦恩图分析表明宜昌酒曲在物种独特性上要优于广西玉林酒曲。本研究揭示了宜昌传统米酒曲中的真菌与玉林传统米酒曲真菌菌种的差别,为逐步改善传统酒曲质量,以及相关微生物的进一步利用提供了理论指导依据。
High-throughput sequencing was used to analyze the microbial community structure of the traditional rice wine starter from Yichang,Hubei and Yulin,Guangxi,and the main microbial species and proportions in the starter were obtained.The species richness and community diversity of Yulin rice wine starter were higher than those of Yichang rice wine starter.The dominant fungal genera in Yulin rice wine starter were Rhizopus,Mucor,Pichia and Candida;the dominant fungal genera in Yichang rice wine starter were Rhizopus and Mucor.The dominant bacterial genera in Yulin rice wine starter were Pediococcus,Pseudomonas,Weissella,and Lactobacillus;the dominant bacterial genera in Yichang rice wine starter were Pseudomonas and Weissella.ASV/OTU Venn diagram showed that Yichang rice wine starter had higher species uniqueness than Yulin rice wine starter.This study reveals the microbial differences between Yichan rice wine starter and Yulin rice wine starter,which provides a theoretical basis for the improvement of the quality of traditional rice wine starter,as well as further utilization of related microorganisms.
