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_012108:442493 Desulfobacterium autotrophicum HRM2, complete genome
Lineage: Desulfobacterium autotrophicum; Desulfobacterium; Desulfobacteraceae; Desulfobacterales; Proteobacteria; Bacteria
General Information: It was isolated from a marine sediment in the Mediterranean sea near Venice, Italy. It is involved in the anaerobic mineralization of organic matter coming from the water column. Desulfobacterium autotrophicum is capable of growing litho-autotrophically with H2, CO2 and sulfate, but also by coupling sulfate reduction with the oxidation of fatty acids. This organism can transform tetra to dichlormethane.
