The degradation of root exudates by the rhizosphere microbiome in +DR was greater than for −DR (P < 0.01). The response of microbial metagenome to polycyclic aromatic hydrocarbons (PAHs) degradation in the rice rhizosphere remains poorly understood. We investigated the spatial and temporal variations of microbial communities and reconstructed metagenomes along the rice rhizosphere gradient during PAHs degradation. Calystegine degradation by bacteria other than S. meliloti Rm41 does not involve the cac genes, as in the latter strain [8, 9], raising the possibility that the rhizosphere microbiota involved in calystegine degradation is highly diverse in terms of both microbial taxonomy and catabolic pathways. The rhizosphere microbe plays an important role in removing the pollutant generated from industrial and agricultural production. To investigate the dynamics of the microbial degradation, a nonlinear mathematical model of the rhizosphere microbial degradation is proposed based on impulsive state feedback control. Phytoremediation has been demonstrated to enhance the degradation of PAHs, but the mechanisms of dissipation have not been identified.

Two review Dissipation of petroleum contaminants in the rhizosphere is likely the result of enhanced microbial degradation.

Most studies reporting root exudate composition were performed with sterile hydroponic systems to avoid microbial degradation of plant metabolites (14). For instance, the model plantArabidopsis thaliana grown in hydroponics exuded a hundred different metabolites repre-senting several chemical classes (15).

The rhizosphere is the ecological zone around plant roots that is saturated with specific metabolic processes that are regulated by root-released substances and by numerous organisms biochemically interacting with the plant and with each other. This paper investigates the potential for rhizosphere degradation of MTBE at time frames relevant for phytoremediation.

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. Rhizodegradation, also known as phyto-stimulation, is the degradation of contaminants in the rhizosphere (area of soil surrounding the roots of the plants) by means of microbial activity which is enhanced by the presence of plant roots.

Leaching, plant uptake, abiotic degradation, mineralization to CO 2 , and irreversible sorption were shown to be insignificant in the overall mass balance of the target compounds.
