Abstract

Studies of polycyclic aromatic hydrocarbon (PAH)-degrading bacteria and plant root exudate enzymes from contaminated rhizospheres suggest that pollutant rhizodegradation involves the joint work of bacteria and plants. Plant-microbial associations with coupled metabolic capabilities that completely degrade PAHs while avoiding the formation of dangerous intermediates are biotechnologically promising.

Keywords: coupled rhizodegradation; peroxidase; plant root exudates; rhizobacteria.
