Query: NC_013939:295220 Deferribacter desulfuricans SSM1, complete genome Lineage: Deferribacter desulfuricans; Deferribacter; Deferribacteraceae; Deferribacterales; Deferribacteres; Bacteria General Information: Thermophilic sulphur-reducing bacterium. Isolated from a deep-sea hydrothermal vent chimney at the Suiyo Seamount in the Izu-Bonin Arc, Japan. Deferribacter desulfuricans is an anaerobic, heterotrophic thermophile. It is a strictly anaerobic heterotroph capable of using complex organic compounds, ethanol and various organic acids as energy and carbon sources. Elemental sulfur, nitrate or arsenate was required for growth as an electron acceptor.

General Information: This symbiotic and thermophilic bacterium was discovered by screening for thermostable tryptanophases in Japanese compost. Cultured growth of this organism requires the presence of another bacterial species, such as a Bacillus or Escherichia coli, which provides diffusable metabolites required for its growth. Pure cultures can be obtained by growing Symbiobacterium thermophilum in a bioreactor, separated from its symbiotic counterpart by a dialysis membrane. Because of its symbiotic nature, it cannot be cultured with conventional methods. Despite a negative reaction for gram stain, this species is placed with the gram-positive bacteria based on 16s phylogenetic analysis.
