中文摘要: 以黄酒熟麦曲为研究对象,采用聚合酶链式反应-变性梯度凝胶电泳(polymerase chan reaction-denaturing gradient gel electrophoresis,PCR-DGGE)与MiSeq 高通量测序技术相结合的方法对其细菌多样性进行解析。DGGE 结果表明:Bacillus(芽孢杆菌)、Weissella(魏斯氏菌)、Pediococcus(片球菌)、Staphylococcus(葡萄球菌)和 Lactobacillus(乳酸杆菌)普遍存在于麦曲样品中。MiSeq 高通量测序结果表明:熟麦曲中的细菌门主要为Firmicutes、Proteobacteria 和Actinobacteria,平均相对含量分别为87.95%、9.00%和1.16%。熟麦曲中的细菌属主要为Bacillus(芽孢杆菌属)、Weissella(魏斯氏属)、Staphylococcus(葡萄球菌)、Klebsiella(克雷伯菌属)、Pantoea(泛菌属)和 Lactobacillus(乳杆菌属),其平均相对含量分别为70.70%、8.55%、2.67%、2.29%、1.32%和1.07%。由此可见,Bacillus(芽孢杆菌)为熟麦曲中的优势细菌。

Abstract:The bacteria diversity of Chinese rice wine cooked wheat Qu samples was analyzed by polymerase chain reaction-denaturing gradient gel electrophoresis(PCR-DGGE)and MiSeq high throughput sequencing.The result of DGGE profile showed that Bacillus,Weissella,Pediococcus,Staphylococcus and Lactobacillus were commonly detected in all wheat Qu samples.Result of MiSeq high-throughput sequencing indicated that Firmicutes,Proteobacteria and Actinobacteria were domain phyla in cooked wheat Qu samples,with the relative abundance of 87.95 % ,9.00 % and 1.16 %.Meanwhile,Bacillus,Weissella,Staphylococcus,Klebsiella,Pantoea and Lactobacillus were domain genera,with the relative abundance of 70.70%,8.55 %,2.67%,2.29%,1.32%and 1.07%,respectively.Thus,the main dominant bacteria in cooked wheat Qu were composed of Bacillus.
