Abstract The bacterial diversity in five Chinese bacon samples collected from Enshi, Hubei was analyzed by polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) and MiSeq high-throughput sequencing. The PCR-DGGE analysis indicated that the microbial flora in Chinese bacon was composed of Staphylococcus, Psychrobacter, Lactobacillus and Pseudoalteromonas. The results of MiSeq high-throughput sequencing indicated that Firmicutes and Proteobacteria were the dominate phyla, with a relative abundance of 54.05% and 44.28%, respectively. Meanwhile, Staphylococcus, Psychrobacter, Pseudoalteromonas, Brochothrix, Cobetia and Acinetobacter were the dominate genera, whose relative abundance was 40.18%, 24.02%, 9.37%, 8.53%, 4.71%, and 2.31%, respectively. A total of 252 operational taxonomic units (OTUs) were shared by all samples whose cumulative average was 74.22% of total qualified sequences. Thus, the dominant bacteria in Chinese bacon were Staphylococcus, Psychrobacter and Pseudoalteromonas.
