desulfococcus oleovorans desulfococcus oleovorans desulfococcus oleovorans is a bacterium from the genus desulfococcus which has been isolated from mud from an oilfield near hamburg in germany. desulfococcus oleovorans scientific classification domain: bacteria phylum: thermodesulfobacteriota class: desulfobacteria order: desulfobacterales family: desulfococcaceae genus: desulfococcus species: d. oleovorans binomial name desulfococcus oleovoransaeckersberg et al. 1991 type strain dsm 6200, hxd3 synonyms candidatus desulfococcus oleovorans strain hxd3 desulfococcus oleovorans dtrain hxd3 was isolated from the saline water phase of an oil-water separator from a northern german oil field. hxd3 is a delta-proteobacterium capable of utilizing c12-c20 alkanes as growth substrates. hxd3 activates alkanes via carboxylation at c3, with subsequent elimination of the terminal and subterminal carbons, yielding a fatty acid that is one carbon shorter than the parent alkane. hxd3 is the only pure culture that is known to carboxylate aliphatic hydrocarbons. the genome of desulfococcus oleovorans has been completely sequenced by the joint genome institute. sequencing is paid for by a department of energy grant to boris wawrik et al. at rutgers university.
