Query: NC_007492:3332839 Pseudomonas fluorescens PfO-1, complete genome

Lineage: Pseudomonas fluorescens; Pseudomonas; Pseudomonadaceae; Pseudomonadales; Proteobacteria; Bacteria

General Information: This strain was isolated from agricultural loam (sand, clay, and organic matter) soil in 1988 by Compeau et al. and is well adapted to soil environments. 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. This organism is a nonpathogenic saprophyte which inhabits soil, water and plant surface environments. If iron is in low supply, it produces a soluble, greenish fluorescent pigment, which is how it was named. As these environmentally versatile bacteria possess the ability to degrade (at least partially) multiple different pollutants, they are studied in their use as bioremediants.

Subject: NC_007951:1711223 Burkholderia xenovorans LB400 chromosome 1, complete sequence

Lineage: Burkholderia xenovorans; Burkholderia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria

General Information: Originally identified as Pseudomonas sp. LB400 that was found in contaminated soil in upstate New York, USA, this organism is now classified in the genus Burkholderia. Polychlorinated biphenyl-degrading bacterium. Member of the genus Burkholderia are versatile organisms that occupy a surprisingly wide range of ecological niches. These bacteria are exploited for biocontrol, bioremediation, and plant growth promotion purposes. Burkholderia xenovorans has been found on fungi, animals, and from human clinical isolates such as from cystic fibrosis (CF) patients. It may be tightly associated with white-rot fungus, as the degadation of lignin by the fungus results in aromatic compounds the bacterium can then degrade. This organism is exceptionally capable of degradation of polychlorinated biphenyls (PCBs), which are environmental pollutants, and thus it may play a role in bioremediation of polluted and toxic sites and is studied as a model bioremediator. PCBs can be utilized as the sole carbon and energy source by this organism. The pathways for degradation of PCBs have been extensively characterized at both the genetic and the molecular level and have become a model system for the bacterial breakdown of these very persistent environmental contaminants.
