Phylogenetic tree showing the relationship of D. formicivorans strain Pf12B^T to other species of the family Desulfomicrobiaceae. Members of the genus Desulfonatronovibrio were used as the outgroup in this analysis. The tree was constructed by the Maximum-Likelihood method with MEGA version 5.1 [16] based on ClustalX version 2.1 [17] aligned sequences of 16S rRNA gene. Bootstrap values (percentages of 1000 replications) of ≥ 50% are shown at nodes. The presence of sequenced genome is indicated with superscripted “*”
