Phylogenetic Analysis of Five Strains of Gram-Negative, Obligately Anaerobic, Sulfur-Reducing Bacteria and Description of Desulfuromusa gen. nov., Including Desulfuromusa kysingii sp. nov., Desulfuromusa bakii sp. nov., and Desulfuromusa succinoxidans sp. nov., Page 1 of 1< Previous page | Next page > /docserver/preview/fulltext/ijsem/44/4/ijs-44-4-753-1.gif
Gram-negative, mesophilic, obligately anaerobic strains Kysw2T (T = type strain), Kyval, and Kyprop isolated from an anoxic mud sample obtained from the Kysing Fjord south of Århus (Denmark) and strains GypropT and GylacT isolated from the Guayamas Basin (Gulf of California) all exhibit complete oxidation of a wide range of electron donors (e. g., dicarboxylic acids and amino acids) linked to stoichiometric reduction of elemental sulfur to hydrogen sulfide. A comparative 16S ribosomal DNA sequence analysis revealed that these five strains, together with a previously described isolate (strain Gö11), constitute a coherent cluster of descent. This cluster belongs phylogenetically to a branch of the delta subclass of the Proteobacteria and is characterized by members of the genera Pelobacter and Desulfuromonas. Within the cluster strains Kysw2T and Kyval, strains Gyprop1 and Kyprop, and strains GylacT and Gö11 have identical 16S ribosomal DNA sequences. The levels of DNA-DNA relatedness were 89% between strains Kysw2T and Kyval, 98% between strains GypropT and Kyprop, and 73% between strains GylacT and Gö11. The levels of DNA-DNA relatedness between members of the three DNA relatedness groups were less than 30%. On the basis of genomic data and phenotypic characteristics, a new genus, Desulfuromusa, is described; this new genus includes three new species, for which the names Desulfuromusa kysingii, Desulfuromusa bakii, and Desulfuromusa succinoxidans are proposed. The type species of the genus Desulfuromusa is D. kysingii. Strains Kysw2 (= DSM 7343), Gyprop (= DSM 7345), and Gylac (= DSM 8270) are the type strains of D. kysingii, D. bakii, and D. succinoxidans, respectively.
