Abstract

Rhizosphere region in the soil is influenced by the presence of plant roots. This influence may be associated with physical change in the area such as compaction or with the deposition of root desired material into the rhizosphere. Rhizosphere is capable of supporting a greater number of microorganisms than bulk, nonvegetated soil. Plants stimulate the growth of microorganisms in the areas around their roots through the release of natural substances. Rhizosphere deposition includes; low molecular weight compounds- sugars, fatty acids, organic acids and synthetic compounds; whereas high molecular weight compounds contain polysaccharides and polygalactic acids. Rhizosphere is a symbiotic association of bacteria, fungi and actinomycetes along the root zone of the plant. Rhizosphere bioremediation is a natural process of degrading xenobiotics which can be enhanced by supplying nutrients and providing suitable environmental conditions. Rhizosphere bioremediation is also known as phytostimulation or plant assisted bioremediation. Mycorhizosphere increases soil organic carbon, bacteria and mycorrhizal fungi all factors that encourage degradation of organic contaminants in soil. Plants enzymes dehydrogenase, nitroreductase, peroxidase, lactase and nitrilase as well as microbial enzymes in mycorhizosphere have made effective biodegradation of complex organic compounds. The present study deals with remediation of polycyclic hydrocarbon in particular anthracene in mycorhizospheric soil. The research findings show that there in rapid degradation of organic compound under the influence of green plant-grasses with fibrous roots in mycorhizosphere. Mycorhizosphere- an ecological remediation unit would be beneficial to decontaminate the xenobiotics to clean up the environment.
