Pan-genome analysis of Bacillus for microbiome profiling.

ABSTRACT: Recent advances in high-throughput sequencing technology allow for in-depth studies on microbial genomes and their communities. While multiple strains of the same species could display genomic variations with different gene contents in diverse habitats and hosts, the essential functions for a specific species are conserved as core genes that are shared among strains. We have comprehensively analyzed 238 strains of five different Bacillus species to identify the properties of core and strain-specific genes. Core and strain-specific genes in each Bacillus species show significant differences in their functions and genomic signatures. Using the core genes defined in this study, we have precisely identified the Bacillus species that exist in food microbiomes. Without resorting to culture-based
