Degradation, phytoprotection and phytoremediation of phenanthrene by endophyte Pseudomonas putida, PD1.

ABSTRACT: Endophytes have been isolated from a large diversity of plants and have been shown to enhance the remediation efficiency of plants, but little information is available on the influence of endophytic bacteria on phytoremediation of widespread environmental contaminants such as polycyclic aromatic hydrocarbons (PAHs). In this study we selected a naturally occurring endophyte for its combined ability to colonize plant roots and degrade phenanthrene in vitro. Inoculation of two different willow clones and a grass with Pseudomonas putida PD1 was found to promote root and shoot growth and protect the plants against the phytotoxic effects of phenanthrene. There was an additional 25-40% removal of phenanthrene from soil by the willow and grasses, respectively inoculated with PD1 when compared to t
