Application of Plant Growth Promoting Rhizobacteria in Bioremediation of Heavy Metal Polluted Soil
The contamination of soil and water with heavy metal pollutants is escalating day by day due to excessive industrialization, waste disposal, agricultural applications and various anthropogenic actions. Accrual of heavy metals, as non biodegradable agents, pose serious environmental concerns for all life forms affecting mostly plants and therefore present a risk to health of humans due to food chain contamination. To avoid heavy metal problems, bioremediation via plant growth promoting rhizobacteria (PGPR) is getting more consideration due to eco friendly nature, less expense and proven efficiency in comparison to physical or chemical remediation methods. Improving growth of plants and conquering the metal toxicity can be enhanced by association of PGPR. These microbes colonize the root or inhabit near root surfaces and involve in mechanisms for plant prevention from toxicity through secretion and production of several regulatory compounds such as phytohormones, siderophores, metal binding proteins etc. The review accentuates the role of PGPR in accelerating phytoremediation for elimination of toxic metals and growth augmentation of plants. Further, explicit spotlight on the exploitation of genetic engineering technology for future PGPR application is highlighted with the aspiration to widen future prospects.
