Query: NC_009485:1487485 Bradyrhizobium sp. BTAi1 chromosome, complete genome
Lineage: Bradyrhizobium; Bradyrhizobium; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This organism is a photosynthetic rhizobium that is also capable of nitrogen-fixation, the first such example of such an organism. It can form nodules on the legume Aeschynomene indica and was isolated from this plant at the Boyce Thompson Institute for Plant Research in Ithaca, NY. It can form stem and root nodules. The photosynthetic reaction centers are similar to those found in purple photosynthetic bacteria and this microbe aids the plant in carbon metabolism and nitrogen metabolism.
Subject: NC_008313:2685531 Ralstonia eutropha H16 chromosome 1, complete sequence
Lineage: Cupriavidus necator; Cupriavidus; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: This strain (ATCC 17699; H16), formerly Alcaligenes eutrophus was originally isolated from sludge. Cupriavidus necator also known as Ralstonia eutropha is a soil bacterium with diverse metabolic abilities. Strains of this organism are resistant to high levels of copper or are able to degrade chloroaromatic compounds such as halobenzoates and nitrophenols making them useful for bioremediation. Other strains have been studied for their ability to produce polyhydroxybutyrates which have industrial application. Another strain is able to attack other bacteria and fungi when nutrients in the soil are low.
