The spatial and temporal variation in the microbial community of yellow-feathered broiler carcasses under penetrated-air packaging (PAP, air filling) and modified-atmospheres packaging (MAP, 80% CO₂ & 20% N₂) was investigated by whole genome sequencing-based metagenomics. The results revealed that MAP prolonged shelf life by 4 days, when the numbers of total plate counts and lactic acid bacteria reached more than 7 log cfu/g. Aeromonas, Acinetobacter, Escherichia and Streptococcus occupied the microbial communities in initial broiler carcasses, and MAP dramatically increased the diversity of microorganisms during storage compared to PAP. Clear shifts of the dominant bacteria species were also observed, with the top genera of Aeromonas, Lactococcus, Serratia and Shewanella in MAP, whereas the microbial communities in PAP were largely dominated by Pseudomonas.
