16S rRNA-based maximum likelihood (ML) phylogenetic tree highlighting position of strain AT3 with closely related species. Corresponding GenBank accession numbers for 16S rRNA genes of each strain are indicated. Sequences were aligned using CLUSTAL W with default parameters and phylogenies were inferred by MEGA 7 software. Branches are scaled in terms of expected number of substitutions per site. Numbers above branches are support values when higher than 75% from ML bootstrapping. Scale bar represents a nucleotide sequence divergence of 2%.
