Query: NC_009092:179226 Shewanella loihica PV-4, complete genome
Lineage: Shewanella loihica; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: This strain is an environmental isolate from the Naha Vents, Hawaii, in the Pacific Ocean. Psychrotolerant bacterium. This genus includes species that inhabit a wide range of environments and are capable of utilizing a wide variety of electron acceptors during anaerobic respiration including some insoluble metal oxides while using very few carbon sources such as lactate or acetate. This group of organisms have been studied extensively for their electron transport systems. Shewanella loihica is a psychrotolerant deep sea bacterium. This organism is able to reduce iron, manganese and uranium and may be useful for bioremediation at low temperatures.
Subject: NC_012808:420334 Methylobacterium extorquens AM1, complete genome
Lineage: Methylobacterium extorquens; Methylobacterium; Methylobacteriaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: First isolated in 1960 in Oxford, England, as an airborne contaminant growing on methylamine. This strain can grow on methylamine or methanol, but not methane. This organism is capable of growth on one-carbon compounds such as methanol. Methanol is oxidized to formaldehyde which is then used metabolically to generate either energy or biomass. These bacteria are commonly found in the environment, especially associated with plants which produce methanol when metabolizing pectin during cell wall synthesis. At least 25 genes are required for this complex process of converting methanol to formaldehyde and this specialized metabolic pathway is of great interest.
