Schematic diagram of the phylogenetic tree of the four strains. The strains of the research group have been marked with emphasis. The strains and their corresponding GenBank accession numbers for 16S rRNA genes are shown following the organism names. Numbers at the branching nodes are percentages of bootstrap values based on 500 replications. Bootstrap values greater than 50% are shown at the branch points. The scale bar represents 0.002 substitutions per nucleotide position
