Query: NC_009937:4768500 Azorhizobium caulinodans ORS 571, complete genome Lineage: Azorhizobium caulinodans; Azorhizobium; Xanthobacteraceae; Rhizobiales; Proteobacteria; Bacteria General Information: This species is a stem-nodulating nitrogen-fixing organism isolated from Sesbania rostrata. Azorhizobium caulinodans ORS571 is a microsymbiont of the water-tolerant tropical legume Sesbania rostrata.A. caulinodans ORS571 is able to fix nitrogen in the free-living state, which is not the case for most rhizobia.

General Information: This green-sulfur bacterium is a thermophile and was isolated from a New Zealand high-sulfide hot spring. Photosynthetic thermophile. Chlorobium tepidum is a member of the green-sulfur bacteria. It has been suggested that the green-sulfur bacteria were among the first photosynthetic organisms since they are anaerobically photosynthetic and may have arisen early in the Earth's history when there was a limited amount of oxygen present. This organism utilizes a novel photosynthetic system, and harvests light energy using an unusual organelle, the chlorosome, which contains an aggregate of light-harvesting centers surrounded by a protein-stabilized galactolipid monolayer that lies at the inner surface of the cytoplasmic membrane. Unlike many other photosynthetic organisms, the green-sulfur bacteria do not produce oxygen and tolerate only low levels of the molecule. This organism also fixes carbon dioxide via a reverse tricarboxylic acid cycle, using electrons derived from hydrogen or reduced sulfur to drive the reaction, instead of via the Calvin cycle like many other photosynthetic organisms.
