Microbial population of a given ecological niche is collectively called as microbiome. Microbiome plays a great role in remediation of heavy metal toxicity in the rhizosphere (soil attached to the plant roots) for safe food production. Rhizospheric microbiome feeds on the contaminants, degrading them for energy and reproduction. Microbial remediation could be categorized into three grades viz. natural attenuation, biostimulation, bioaugmentation. Among these three, bioaugmentation has taken more attention due to higher substrate specificity, efficiency and sustainability. Therefore, in addition to brief introduction of natural attenuation and biostimulation, the present study will discuss the basic mechanisms of how bioaugmentation effectively detoxify rhizospheric toxic metal especially arsenic (As) and how to develop novel strain for As detoxification through bioaugmentation.
