NC_010322:1 Pseudomonas putida GB-1 chromosome, complete genome
Host Lineage: Pseudomonas putida; Pseudomonas; Pseudomonadaceae; Pseudomonadales; Proteobacteria; Bacteria
General Information: Pseudomonas putida strain GB-1, a fresh water, Gram-negative gamma-proteobacterium, is a genetically tractable, robust manganese (Mn) oxidizer, and as such, is an ideal model for unraveling the catalytic mechanism for, and the molecular regulation of Mn(IV) oxide production and its eventual accumulation on the cell surface at the onset of stationary phase. Since its isolation from Green Bay nearly 20 years ago by Ken Nealson’s group (then at the Center for Great Lakes Studies, Univ. Wisconsin-Milwaukee, USA), it has been the non spore-forming, model organism (along with the closely-related strain MnB1) for molecular genetic studies of Mn(II) oxidization, protein transport and biofilm formation and for biochemical studies on protein purification and Mn(III)-pyoverdine binding. Bacteria belonging to the Pseudomonas group are common inhabitants of soil and water and can also be found on the surfaces of plants and animals. Pseudomonas bacteria are found in nature in a biofilm or in planktonic form. Pseudomonas bacteria are renowned for their metabolic versatility as they can grow under a variety of growth conditions and do not need any organic growth factors. As they are metabolically versatile, and well characterized, it makes them great candidates for biocatalysis, bioremediation and other agricultural applications. Certain strains have been used in the production of bioplastics.
