Plant–Microbe Interaction: A Potential Tool for Enhanced Bioremediation

A number of toxic and synthetic organic compounds are a problem worldwide because they can contaminate environmental soil through either local (e.g., industrial) or diffuse (e.g., agricultural) contamination. These pollutants have negative effects on environment as well as human health. In order to clean the polluted sites, the search for alternative methods for excavation and incineration resulted in the application of bioremediation techniques. Rhizoremediation is a specific form of phytoremediation and bioaugmentation that could be applied to solve the problems encountered by the application of these techniques individually. During rhizoremediation, root exudates stimulate the survival and action of bacteria, which subsequently result in efficient degradation of pollutants. The root system of plants can help bacteria to spread through soil and penetrate even impermeable soil layers. The main contributors for rhizoremediation include endophytic and rhizospheric bacteria. These bacteria have potential for improving bioremediation of toxic organic compounds in contaminated sites. The efficiency of phytoremediation or bioaugmentation can be improved by inoculation of pollutant-degrading bacteria on plant seed.
