三种典型白酒环境微生物群落结构解析、酿造微生物溯源及功能特性OA

As three typical types of Baijiu,the strong-flavor(Nongxiangxing)Baijiu,sauce-flavor(Jiangxiangxing)Baijiu,and Daqu light-flavor(Qingxiang-xing)Baijiu were all distilled spirits that produced in open-environment using grains as raw materials and Daqu as saccharification and fermentation agent.The open production mode makes the effect of environmental microorganisms on the three typical types of Baijiu non-negligible.With the development of technologies such as amplicon sequencing and metagenomics,the impact of environmental microorganisms on the micro-ecology of Baijiu brewing has gradually been analyzed.The analysis methods of environmental microbial communities,community structure analysis and influencing factors of three typical types of Baijiu were summarized,traceability analysis of Baijiu brewing microorganisms was carried out,and functional characteristics of brewing microorganisms was outlined,aiming to provide reference for analyzing environmental microbial community structure,exploring the effect of environmental microorganisms on Baijiu fermentation process,and shaping an environmental micro-ecology conducive to Baijiu fermentation.
