Endophytic Burkholderia fungorum DBT1 can improve phytoremediation efficiency of polycyclic aromatic hydrocarbons.

Burkholderia fungorum DBT1 is a bacterial strain isolated from an oil refinery discharge and capable of transforming dibenzothiophene, phenanthrene, naphthalene, and fluorene. In order to evaluate the influence of a policyclic aromatic hydrocarbon (PAH)-transforming bacterial strain on the phytoremediation of organic contaminants, B. fungorum DBT1 was inoculated into hybrid poplar (Populus deltoides×Populus nigra).
