Soil bacteria are very vital and they are frequently used in production of crop. Chemical dialogues between bacteria and plant roots result in the proliferation and biofilm formation of plant growth promoting and contaminant degrading bacteria. Plant-bacterial interactions in the rhizosphere are the determinants of plant health and soil fertility. Plant growth promoting rhizobacteria (PGPR) which is also known as plant health promoting rhizobacteria (PHPR) or nodule promoting rhizobacteria (NPR). It can benefit the host plant directly by enhancing plant growth or indirectly by producing hydrolytic enzymes and by priming plant defence. This review elaborates the effect of plant and bacterial products on the remediation of contaminated soil.
