Query: NC_008344:1 Nitrosomonas eutropha C91, complete genome
Lineage: Nitrosomonas eutropha; Nitrosomonas; Nitrosomonadaceae; Nitrosomonadales; Proteobacteria; Bacteria
General Information: Nitrosomonas eutropha C91 was isolated from a sewage disposal plant in Chicago. Ammonia-oxidizing bacterium. This species consists of ammonia-oxidizing bacteria that catalyze the oxidation of ammonia to nitrite and contribute to the global cycling of nitrogen (a process called nitrification). This obligate chemolithoautotroph is studied for that reason.
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.
