Abstract

A novel type of dissimilatory sulfate-reducing bacterium, designated strain RS-1^T, capable of producing intracellular magnetite particles (magnetosomes) was isolated from freshwater sulfide-rich sediments. Phylogenetic analysis based on 16S rDNA sequences revealed that RS-1^T is a member of the genus Desulfovibrio. Its closest known relative is Desulfovibrio burkinensis (sequence similarity of 98.7%). Strain RS-1^T contains desulfoviridin, c-type cytochromes and, unlike other Desulfovibrio spp., it possesses menaquinone MK-7(H₂) instead of MK-6 or MK-6(H₂). Strain RS-1^T is also unique compared with other members of Desulfovibrio in its ability to synthesize intracellular magnetite particles. A novel species, Desulfovibrio magneticus sp. nov., is proposed for RS-1^T (= ATCC 700980^T = DSM 13731^T), a sulfate-reducing magnetotactic bacterium.
