该研究通过高通量测序技术解析不同种类高温大曲(黄曲、黑曲、白曲、综合曲)中真菌多样性与群落结构,基于属水平对其真菌菌群进行聚类分析(CA)及主坐标分析(PCoA),并对其真菌菌群进行系统发育分析.结果表明,黄曲中真菌群落丰富度最高,其特有的扩增子序列变体(ASVs)为790个;黄曲中优势菌门为子囊菌门(Ascomycota),优势菌属为嗜热真菌属(Thermomyces)、嗜热子囊菌属(Thermoascus)、曲霉属(Aspergillus)、红曲霉属(Monascus)等;CA及PCoA结果表明,在属水平下,黄曲与黑曲之间真菌群落结构相似度更高;真菌菌群系统发育分析表明,黄曲中Aspergillus的相对丰度均高于其他高温大曲.该研究为采用微生物技术改良酒曲,提高浓香型白酒品质与风味提供理论依据.
Analysis of fungi community diversity and structure in different high-temperature Daqu
In this study,the fungal diversity and community structure of different high-temperature Daqu(yellow Qu,black Qu,white Qu,mixed Qu)were analyzed by high-throughput sequencing technology,the fungal community were analyzed by cluster analysis(CA)and principal coordinate anal-ysis(PCoA)based on the genus level,and the phylogenetic analysis of the fungal community was conducted.The results shown that the richness of fungal community in yellow Qu was the highest,the unique amplicon sequence variants(ASVs)was 790.Ascomycota was the dominant phyla in yel-low Qu,and Thermomyces,Thermoascus,Aspergillus,and Monascus,etc were the dominant genera.CA and PCoA results showed that on the genus level,the similarity of fungal community structure between yellow Qu and black Qu was higher.Phylogenetic analysis of fungal flora showed that the relative abundance of Aspergillus in yellow Qu was higher than that in other high-temperature Daqu.The study provided a theoretical basis for im-proving Jiuqu by microbial technology and improving the quality and flavor of sauce-flavor(Nongxiangxing)Baijiu.
