Phylogenetic tree highlighting the position of
MEV2011 (shown in red) relative to closely related (≥95% sequence similarity) type strains within the
. Pre-aligned sequences were retrieved from the Ribosomal Database Project (RDP) . Alignment of the B. azotoformans MEV2011 sequence as well as manual alignment optimization was performed in ARB . The maximum likelihood tree was inferred from 1,478 aligned positions of 16S rRNA gene sequences and calculated based on the General Time Reversible (GTR) model with gamma rate heterogeneity using RAxML 7.4.2 . Type strains with corresponding published genomes are shown in bold face. Open and closed circles indicate nodes with bootstrap support (1,000 replicates ) of 50-80% and >80%, respectively. Escherichia coli ATCC 11577T (X80725) was used to root the tree (not shown). Scale bar, 0.1 substitutions per nucleotide position.
