Two recently reported bacterial strains that are able to reductively dehalogenate polychlorinated aliphatic alkanes, including 1,2,3-trichloropropane, 1,2-dichloropropane, 1,1,2,2-tetrachloroethane, 1,1,2-trichloroethane and 1,2-dichloroethane, were further characterized to clarify their taxonomic position. The two strains, designated BL-DC-8 and BL-DC-9T, were mesophilic, non-spore-forming, non-motile, Gram-negative staining and strictly anaerobic. Cells were irregular cocci, 0.3–0.6 μm in diameter. The two strains were resistant to ampicillin and vancomycin. Hydrogen was utilized as an electron donor. The genomic DNA G+C content of strains BL-DC-8 and BL-DC-9T was 54.0 and 53.8 mol%, respectively. The major cellular fatty acids were C18 : 1 ω9c, C16 : 1 ω9c, C16 : 0 and C14 : 0. Phylogenetic analyses based on 16S rRNA gene sequences indicated that the strains cluster within the phylum Chloroflexi, but are related only distantly to all recognized taxa in the phylum. Morphological, physiological and chemotaxonomic traits as well as phylogenetic analysis support the conclusion that these two strains represent a novel species of a new genus in the phylum Chloroflexi, for which the name Dehalogenimonas lykanthroporepellens gen. nov., sp. nov. is proposed. The type strain of Dehalogenimonas lykanthroporepellens is BL-DC-9T (=ATCC BAA-1523T =JCM 15061T).
-
The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of strains BL-DC-9T and BL-DC-8 are EU679419 and EU679418, respectively.
-
Scanning electron and transmission electron micrographs of cells of strains BL-DC-9T and BL-DC-8 and phenotypic characteristics of type species of genera in the phylum Chloroflexi are available with the online version of this paper.
