Phenotypic and phylogenetic studies were performed on a novel sulfate-reducing bacterium, strain D41T, isolated as part of a methanogenic syntrophic culture from a gas condensate-contaminated aquifer undergoing intrinsic bioremediation. The bacterium was a Gram-negative, non-spore-forming, curved rod, motile by a single polar flagellum, which oxidized several alcohols incompletely, including methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, 3-methyl-1-butanol (isoamyl alcohol), ethylene glycol, 1,2-propanediol, 1,3-propanediol, 1,4-butanediol, phenylethanol and benzyl alcohol. Additionally, the strain oxidized H2/CO2, formate, lactate, pyruvate, maleate, malate and fumarate. Sulfate, thiosulfate and sulfite were used as electron acceptors. The DNA G+C content was 63 mol%. Based on phylogenetic and phenotypic evidence, the novel species Desulfovibrio carbinoliphilus sp. nov. is proposed. The type strain is D41T (=ATCC BAA-1241T =DSM 17524T).

Abbreviations: BTEX, benzene, toluene, ethylbenzene and isomers of xylene; SRB, sulfate-reducing bacteria(um)

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain D41T is DQ186200.

A transmission electron micrograph of a cell of strain D41T and graphs showing conversion of benzyl alcohol to benzoate in pure culture and co-culture are available as supplementary material with the online version of this paper.
