摘要: 采用高通量测序技术对河南省某酒企中温大曲曲皮和曲心两个部位的真菌群落和细菌群落的多样性及其组成进行了研究.结果表明:1)中温大曲曲皮样品中真菌群落多样性和丰度均高于曲心样品;子囊菌门是大曲曲皮和曲心样品中的唯一优势菌门;大曲样品中共检测到15种真菌,其中扣囊复膜孢酵母、雪黄散囊菌和毕赤酵母sp1为曲皮和曲心样品中的优势真菌,扣囊复膜孢酵母在曲皮和曲心样品中的含量基本一致,而雪黄散囊菌和毕赤酵母sp1在曲皮和曲心样品中的含量差异较大.2)中温大曲曲心样品中细菌群落多样性高于曲皮样品,但其丰度低于曲皮样品;在大曲样品中共检测到28个属,其中肠杆菌属、乳杆菌属、乳球菌属、布氏杆菌属、肠球菌属和欧文氏菌属为大曲样品中的优势细菌属,除布氏杆菌属外,其他优势细菌属在曲皮和曲心样品中的含量差异较大.Abstract: The diversity and structure of fungal and bacterial communities in Qupi and Quxin of medium temperature Daqu from one wine corporation located in He'nan were analyzed based on the high-throughput sequencing technology.The results showed that:1) The diversity and abundance of fungal community in Qupi were higher than those in Quxin samples,and Ascomycetes was the only dominant fungi detected both in Qupi and Quxin.A total of 15 species of fungi was detected in Daqu,of which Saccharomycopsis fibuligera,Eurotium niveoglaucum,Pichia sp1 were the dominant fungi in Qupi and Quxin samples.Among them,the content of Saccharomvcopsis fibuligera in Qupi was similar to that in Quxin,however,the contents of Eurotium niveoglaucum and Pichia sp1 in Qupi and Quxin samples were quite different.2) The diversity of bacterial community in Quxin of medium temperature Daqu was higher than that of Qupi,but its abundance was lower than that of Qupi.A total of 28 genera was detected in the Qupi and Quxin samples,of which Enterobacter,Lactobacillus,Lactococcus,Brucella,Enterococcus and Erwinia were dominant bacteria of Daqu samples.Expect for Brucella,the content of other dominant bacteria had a large difference in Qupi and Quxin.
