Synergetic Action of Rhizobiome in Bioremidiation of Organic Pollutants

Pollution can be remediated by physical, chemical, and biological means. However, bioremediation has become increasingly popular as it possesses the biochemical and ecological capacity to degrade organic pollutants and making useful for rehabilitating contaminated soils in a comparatively safer and sustainable way. The rhizobiome is the microbial community nitrogen-fixing densely populating in the immediate environment of plant root system. More specifically the rhizobiome are widely distributed in the soil and root ecosystems. The synergistic action of multiple rhizobial strains enhances both plant growth and remediation of pollutants. With ample amount of nitrogen supply it reduces the need for fertilizers and stimulates the survival of other biodegrading bacteria and thereby lowers the concentration of pollutants. This review of recent advances on nitrogen fixing rhizobiome using biochemical and molecular mechanisms provides a new avenue for the rehabilitation of contaminated soils.
