Query: NC_009445:7220929 Bradyrhizobium sp. ORS 278 chromosome, complete genome

Lineage: Bradyrhizobium; Bradyrhizobium; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: This strain was isolated from an Aeschynomene stem nodule and is photosynthetic, which is a rare trait in Rhizobium bacteria. These strains exhibit a photoheterotrophic and strictly aerobic photosynthesis. In culture, most stem isolates show the same pink coloration, while a few strains produce orange pigmentation. Pigment analyses showed that bacteriochlorophyll and spirilloxanthin, two pigments of the light harvesting system, are common to all of these photosynthetic Bradyrhizobium strains, whereas orange strains produce an additional bicyclic carotenoid, canthaxanthin (4,4'-diketo-beta-carotene). Bradyrhizobium sp. strain ORS278 produces the highest quantity of canthaxanthin of all tested photosynthetic bacteria; canthaxanthin represents 85% of its total carotenoid content.

Subject: NC_007974:2097334 Ralstonia metallidurans CH34 chromosome 2, complete sequence

Lineage: Cupriavidus metallidurans; Cupriavidus; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria

General Information: This strain was first identified in the heavy metal-contaminated sludge of a settling tank in Belgium in the late 1970s. This organism, formerly Ralstonia metallidurans, is capable of growth in the presence of a large number of heavy metals including silver, cadmium, chromium, cobalt, copper, mercury, nickel, lead, thallium, and zinc.
