Query: NC_014624:2668157 Eubacterium limosum KIST612 chromosome, complete genome
Lineage: Eubacterium limosum; Eubacterium; Eubacteriaceae; Clostridiales; Firmicutes; Bacteria
General Information: Eubacterium limosum KIST612 is an acetogenic bacterium isolated from an anaerobic digester and has a high growth rate on synthesis gas (CO; carbon monoxide) using it as a sole energy source. This organism produces acetate as well as butyrate and ethanol as fermentation products from syngas. Therefore, E. limosum KIST612 has been considered for a model strain for bioenergy production from syngas (obtained from biomass).
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.
