Genus species

Description and significance

Paraburkholderia are largely known for their ability to degrade aromatic compounds and many hydrocarbons. Recent phylogenomic evidence has divided Paraburkholderia from Burkholderia (1). Some species of this genera have the ability to form root nodules that fix atmospheric nitrogen. The metabolic capabilities of Paraburkholderia has created notable interests in the biodegradation field, where the ability of these species of bacteria to break down pollutants in soil (1). There is special focus on the breakdown of PAHs, or organic pollutants known as polycyclic aromatic hydrocarbons created from pollution.

Genome structure

There are currently around 50-60 available genomes for Paraburkholderia. Diverse metabolic activity stems from its rather large genome of 7-10 Mb. Common G+C content of many Paraburkholderia species is 60-62% (2). Genomic DNA from strain RP11T was a strain of interest and sequenced at the Cornell University Sequencing Facility. The DNA sequencing of each strain of this bacteria proved to show advantages of metabolic decomposition of aromatic compounds. RP11T had different genomic factors from its close relatives, as it encoded the greatest number of genes in RAST (Rapid Annotations using Subsystem Technologies) for the metabolism of aromatics along with a great number of oxidases for aromatic-degradation (1). Additionally, a high number of encoded oxidizing enzymes were recognized in some strains, where all Paraburkholderia encode for the capability to grow on 4-hydroxybenzoic acid.
