Query: NC_007912:4125970 Saccharophagus degradans 2-40, complete genome

Lineage: Saccharophagus degradans; Saccharophagus; Alteromonadaceae; Alteromonadales; Proteobacteria; Bacteria

General Information: This strain is a marine gamma-proteobacterium that was isolated from decaying Spartina alterniflora, a salt marsh cord grass, in the Chesapeake Bay, USA. Saccharophagus degradans 2-40 has been used to produce ethanol from plant material and may be useful for the production bioethanol. Bacterium able to degrade complex carbohydrates. Saccharophagus degradans is capable of degrading insoluble complex carbohydrates through the collective action of enzyme complexes found on its cell surfaces, utilizing the degradation products as a carbon source. This organism may be useful in bioremediation. The degradative enzymes this organism produces are typically exoenzymes that are collected and organized into large surface complexes termed cellulosomes.

Subject: NC_008380:4532969 Rhizobium leguminosarum bv. viciae 3841, complete genome

Lineage: Rhizobium leguminosarum; Rhizobium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: This biovar nodulates legumes in the Tribe Viciae (Vicia, Pisum, Lathyrus, Lens). This strain is a spontaneous streptomycin-resistant mutant of strain 300. Nitrogen-fixing plant symbiont. This organism, like other Rhizobia, establishes a symbiotic relationship with a legume plant, providing nitrogen in exchange for a protected environment. The legume roots secrete flavonoids and isoflavonoids which the bacteria recognize and use to turn on genes involved in root nodulation. Many of the root nodulation genes are involved in synthesis and secretion of a nodule inducing signal, a lipochito-oligosaccharide molecule, which the plant recognizes, triggering nodule formation. The bacterium is endocytosed and exists inside a membrane bound organelle, the symbiosome, and fixes nitrogen for the plant cell while the host cell provides carbon compounds for the bacterium to grow on. The nitrogen fixation is important as it obviates the need for expensive and environmentally damaging fertilizer use.
