Query: NC_014733:2201485 Methylovorus sp. MP688 chromosome, complete genome Lineage: Methylovorus; Methylovorus; Methylophilaceae; Methylophilales; Proteobacteria; Bacteria General Information: Methylotrophic bacteria are a group of bacteria which are able to grow aerobically at the expense of methanol as the sole source of carbon and energy, and therefore could serve as biocatalysts for the conversion of methanol to commercially valuable multicarbon compounds like amino acids and cytochromes. Pink-pigmented facultative methylotrophs of the genus Methylovorus are ubiquitous in soil, air and water environments. The MP688 strain was isolated from soil as an PQQ producer.

General Information: This organism was first isolated from the soil in Vineland, New Jersey, although it is found worldwide. It is a large obligate aerobe that has one of the highest respiratory rates of any organism. Azotobacter vinelandii also produces a number of unusual nitrogenases which allow it to fix atmospheric nitrogen to ammonia, a compound it can then use as a nitrogen source. It protects the oxygen-sensitive nitrogenase enzymes through its high respiratory rate, which sequesters the nitrogenase complexes in an anoxic environment. This organism has a number of unusual characteristics. Under extreme environmental conditions, the cell will produce a cyst that is resistant to dessication and is surrounded by two capsular polysaccharide layers. This organism produces two industrially important polysaccharides, poly-beta-hydroxybutyrate (PHB) and alginate. PHB is a thermoplastic biopolymer, and alginate is used in the food industry. Alginate is also used by the pathogen Pseudomonas aeruginosa to infect the lungs of cystic fibrosis patients.
