Strain PerGlyS clustered with representatives of the δ subclass of the class Proteobacteria, close to “Desulforhopalus vacuolatus” but sufficiently distinct to preclude its assignment to this genus. These organisms, together with Desulfobulbus propionicus, represent a phylogenetic subgroup among members of the δ subclass of Proteobacteria. Strain FIGIyR was found to cluster with the gram-positive bacteria with low-G+C DNA, and Desulfitobacterium dehalogenans and Desulfotomaculum orientis are its closest relatives. Other species of the genus Desulfotomaculum are phyloge-netically only moderately closely related to these organisms. These results necessitate the establishment of new genera and species for these two strains. Strain PerGlyS was designated the type strain of Desulfofustis glycolicus gen. nov., sp. nov., and strain FIGIyR was designated the type strain of Syntrophobotulus glycolicus gen. nov., sp. nov. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-46-4-1065
