为比较不同品牌的浏阳豆豉中真菌分布情况,采用ITS高通量测序对4种品牌的浏阳豆豉(LJ,TPQ,TMS,YPX)中真菌组成进行检测,并通过韦恩图、热图和主坐标分析(PCoA)对其结果进行分析.结果表明,4种豆豉存在共有的146个操作分类单元(OTUs),TPQ豆豉样品的真菌相对丰度最大,LJ豆豉样品最低.4种浏阳豆豉均以子囊菌门(Ascomycota)、毛霉亚门(Mucoromycota)为主要菌群门类,LJ和YPX豆豉样品中均以曲霉属(Aspergillus)为主要菌属,其中LJ豆豉中曲霉属相对丰度最高(91.4％),TPQ豆豉样品中小囊菌属(Microascus)相对丰度最高(49.1％).热图聚类结果反映出各品牌浏阳豆豉中具有其特有的菌属,横梗霉属(Lichtheimia)主...

In order to compare the distribution of fungus in different brands of Liuyang Douchi,the community structure of fungus in Liuyang Douchi of 4 brands(LJ,TPQ,TMS,YPX)was determined by ITS high-throughput sequencing,and the results were analyzed by Venn,heatmap and principal coordinate analysis(PCoA).The results showed that there were 146 operational taxonomic units(OTUs)in total among the 4 types of Douchi samples,the fungal relative abundance was the highest in TPQ Douchi sample and was the lowest in LJ Douchi sample.Ascomycota and Mucoromycota were main phyla in all samples,and Aspergillus was...
