Metabonomic Heterogeneity of Extracellular Metabolites of Three Bacillus Genera

Based on metabonomics,229 extracellular metabolites from three Bacillus genera were identified by GC/MS.PCA and hierarchical cluster analysis showed that the metabonomics differed among the genera,but were similar within same genus.The strains in a genus could be clustered into one group.The strains of Paenibacillus and Bacillus clustered into one subgroup,and the stains of Brevibacillus clustered into another subgroup.In this study,three metabolic markers were identified for the three Bacillus genera.
