Rhizoremediation is a technique which uses the rhizospheric microbiota to remediate the pollutants. Dehydrogenase enzyme is considered to exist in soil as integral part of intact cells. Dehydrogenase activity in soils provide correlative information on the biological activity and microbial populations in the soil. When AM fungal spores were added to the phytoremediating legume plants the dehydrogenase activity tends to increase up to levels of control where no pollutant was present. The highest increase was found in Cicer arientinum on addition of AM fungal spores i.e. 16.4 μg INTF g-1 soil in control but rhizoremediated treatment gave increased activity up to 40.7μg INTF g-1 soil. Phaseolus mungo shows a very minimal difference in all three treatments.
