Query: NC_010506:2146444 Shewanella woodyi ATCC 51908, complete genome
Lineage: Shewanella woodyi; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: This luminous species was isolated from squid ink and seawater from depths of 200 to 300 m in the Alboran Sea. This respiratory (nonfermentive) organism is able to use nitrate or nitrite as a terminal electron acceptor. This organism is motile via a single polar flagellum.
Subject: NC_006177:835459 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.
