Desulfobulbus aggregans sp. nov., a Novel Sulfate Reducing Bacterium Isolated from Marine Sediment from the Gulf of Gabes.

Three sulfate-reducing bacterial strains designated SM40, SM41, and SM43 were isolated from marine sediment in the region of Skhira located in the Gulf of Gabes (Tunisia). These strains grew in anaerobic media with phosphogypsum as a sulfate source and sodium lactate as an electron and carbon source. One of them, strain SM40, was characterized by phenotypic and phylogenetic methods.
