Query: NC_008048:389645 Sphingopyxis alaskensis RB2256, complete genome
Lineage: Sphingopyxis alaskensis; Sphingopyxis; Sphingomonadaceae; Sphingomonadales; Proteobacteria; Bacteria
General Information: Isolated from Resurrection Bay in the Gulf of Alaska. It is a model oligotrophic organism and forms a very small cell size. his genus was created from the Sphingomonas genus on the basis of phylogenetic, phenotypic, and chemotaxonomic characteristics. Sphingopyxis alaskensis is one of the most numerically abundant microbes found in oligotrophic marine waters and is an important contributor of biomass.
Subject: NC_009049:80184 Rhodobacter sphaeroides ATCC 17029 chromosome 1, complete sequence
Lineage: Rhodobacter sphaeroides; Rhodobacter; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: A photosynthetic bacterium useful in bioremediation. Anoxygenic photosynthesis, Carbon fixation, Nitrogen fixation. 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.
