Query: NC_009445:6621996 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_007494:1 Rhodobacter sphaeroides 2.4.1 chromosome 2, complete sequence

Lineage: Rhodobacter sphaeroides; Rhodobacter; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria

General Information: Isolated from deep lakes and stagnate waters. A photosynthetic bacterium useful in bioremediation. Bacteria belonging to the Rhodobacter group are metabolically versatile as they are able to grow using photosynthesis, chemosynthesis, and usually can grow under both anaerobic and aerobic conditions. It can grow aerobically and anaerobically in the light and anaerobically in the dark. It produces an intracytoplasmic membrane system consisting of membrane invaginations where the light harvesting complexes (LH1 and LH2) and the reaction center are synthesized.
