摘    要:为探究徽派腊肉加工过程中的微生物群落演替规律,采用高通量测序技术对不同加工阶段的徽派腊肉中微生物16S rRNA进行V3~V4区测序,比较不同加工阶段(鲜肉、腌制中期、腌制结束、成熟中期、成熟结束)腊肉中细菌群落结构组成及多样性差异.结果表明:5个加工阶段分别获得80155、80116、80174、80114、8017...

关 键 词:徽派腊肉  高通量测序  发酵  微生物群落  细菌多样性

Abstract:High throughput sequencing was used to investigate the microbial community succession of Hui-style bacon samples at different processing stages (fresh meat, mid-curing, the end of curing, mid-maturation and the end of maturation). The V3-V4 region of the bacterial 16S rRNA gene was sequenced to compare the composition and diversity of bacterial community among the processing stages. The results showed that 80 155, 80 116, 80 174, 80 114 and 80 174 effective sequences were obtained for the five processing stages, respectively. At the phylum level, Firmicutes, Proteobacteria, Actinomycetes and Bacteroides were dominant. At the genus level, Lactococcus and Pseudomonas were the dominant bacteria in fresh meat, at the mid-curing stage and at the end of curing, while Staphylococcus, Salinivibrio and Actinomycetes were the dominant bacteria at the mid-maturation stage and at the end of maturation. These findings showed that different processing stages had significant effects on the microbial community structure and diversity in Hui-style bacon.
Keywords:Hui-style bacon  high throughput sequencing  fermentation  microbial community  bacterial diversity
