Neighbor-joining (NJ) phylogenetic tree based on 16S rRNA gene sequences showing the position of strain AK-R2A1-2 ^T. Bootstrap values (> 50%) were calculated using the NJ, maximum-likelihood (ML), and minimum evolution (ME) algorithms. Filled circles on the nodes indicate that the relationships were also identified using the ML and ME algorithms, whereas open circles indicate nodes were identified by either the ML or the ME algorithm. Scale bar: 0.0100 substitutions per nucleotide position.
