摘　　要：为了探究不同生态环境中生产的酱香型白酒风味和品质差异,该研究采用高通量测序技术解析古蔺和建瓯代表酱香型白酒生产企业厂区环境土壤和空气真菌群落结构。结果表明,酱香型白酒古蔺厂区环境土壤的真菌物种丰富度和群落多样性高于建瓯厂区,而空气真菌物种丰富度和群落多样性低于建瓯产区。两个厂区环境优势真菌群落结构在门、属水平上大致相似,两个厂区共有的土壤和空气真菌属分别为69种,45种,占土壤和空气真菌菌属总数的14.98%。当线性判别分析(LDA)阈值>3.5时,两个酱香型白酒产区包含以冠突散囊菌属(Eurotium)、嗜热真菌属(Thermomyces)、复膜孢酵母属(Saccharomycopsis)为代表的41个显著差异的真菌属。由此可见,古蔺和建瓯产区环境真菌群落结构上存在明显差异,也进一步证实了不同产区拥有独特的酿酒微生物生态环境。In order to explore the differences in flavor and quality of sauce-flavor(Jiangxiangxing)Bajiu produced in different ecological environments,the environmental soil and air fungal community structure of the representative sauce-flavor Baijiu production enterprises factory area of Gulin and Jian'ou were analyzed by high-throughput sequencing technology.The results showed that the fungal species richness and community diversity in the environmental soil of Gulin factory area were higher than that in Jian'ou factory area,while the air fungal species richness and community diversity were lower than those in Jian'ou factory area.The structure of environmental dominant fungal communities in the two factory areas was roughly similar at phyla and genus level,and the soil and air fungal genera shared by the two factory areas were 69 and 45,respectively,which accounted for 14.98%of the total fungi genera of soil and air.When the linear discriminant analysis(LDA)threshold was>3.5,the two sauce-flavor Baijiu producing areas contain 41 significantly differential fungi genera,including Eurotium,Thermomyces and Saccharomycopsis.Therefore,it could be seen that there were obvious differences in the environmental fungal community structure between Gulin and Jian'ou,which further proved that different producing areas have a unique wine microbial ecological environment.
