Chemical pollution consider one of the most pressing environmental challenges that we face. It is imperative that we address the environmental hazards associated with chemical pollutants. Polyaromatic hydrocarbons (PAHs) and halogenated compounds because of their considerable toxicity and recalcitrant nature, are particularly concerning pollutants. The hydrophobicity among PAHs also increases human health risks by promoting bioaccumulation in the fatty tissue. Thus, the determination of effective and cost efficient methods for removal or degradation of PAHs is essential. , Bacterial bioremediation, under in situ conditions, is a promising strategy for reducing polyaromatic hydrocarbons pollution.
A major challenge associated with bacterial bioremediation is that established bacterial communities with any microbes introduced for bioremediation. Furthermore, poor soil conditions are often associated with contaminated sites and inhibit many potential bioremediation bacteria. Actinorhizal plants are able to reclaim and colonize these harsh environments and contaminated lands including industrial wastelands (Roy et al 2007, Ridgeway et al 2004, Normand et al 2014). These plants form a symbiotic nitrogen-fixing association with Frankia, a soil-dwelling actinobacteria that enables this colonization process. The worldwide distribution of actinorhizal plants covers an expansive range of ecological conditions from dry sandy areas, chaparrals and deserts, to wetlands, forests and
