Query: NC_007907:321537 Desulfitobacterium hafniense Y51, complete genome
Lineage: Desulfitobacterium hafniense; Desulfitobacterium; Peptococcaceae; Clostridiales; Firmicutes; Bacteria
General Information: This strain was isolated from soil contaminated with tetrachloroethene (PCE) in Japan. It can efficiently dehalogenate PCEs via trichloroethene (TCE) to cis-1,2-dichloroethene (cis-1,2-DCE). It can also dehalogenase tetra-, penta-, and hexachloroethanes. Hydrocarbon dehalogenator. This organism can dehalogenate a variety of hydrocarbons and can utilize fumarate, sulfite, and thiosulfate (but not thiousulfate) as terminal electron acceptors. Some important pollutants such as polychlorinated biphenyls (PCBs) may be degraded by this organism.
Subject: NC_006177:12383 Symbiobacterium thermophilum IAM 14863, complete genome
Lineage: Symbiobacterium thermophilum; Symbiobacterium; Shewanellaceae; Clostridiales; Firmicutes; Bacteria
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.
