Query: NC_010524:2761394 Leptothrix cholodnii SP-6, complete genome
Lineage: Leptothrix cholodnii; Leptothrix; Comamonadaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: Leptothrix cholodnii SP-6 was isolated from water and flocculent from an artificial iron seep in Ithaca, NY, USA. Leptothrix cholodnii, like other Leptothrix species is an iron- and manganese-oxidizing, sheathed bacterium common in organic rich aquatic environments. Iron oxides and manganese oxides often coat the sheathes of these organisms.
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.
