Phylogenetic tree highlighting the position of Brevibacillus massiliensis strain phRT relative to other type strains within the Brevibacillus genus. GenBank accession numbers are indicated in parentheses. Sequences were aligned using CLUSTALW, and phylogenetic inferences obtained using the maximum-likelihood method within MEGA program. Numbers at the nodes are percentages of bootstrap values obtained by repeating the analysis 500 times to generate a majority consensus tree. Alicyclobacillus acidocaldarius was used as outgroup. The scale bar represents a 2% nucleotide sequence divergence.
