Abstract :
Environmental pollution is the release of chemical waste that causes detrimental effects on the environment. Contaminants such as metals, pesticides, solvents, explosives, and crude oil and its derivatives, have been mitigated in phytoremediation and bioremediation projects worldwide. The main difference between phytoremediation and bioremediation is that the bioremediation is the use of living organisms either to degrade, detoxify, transform, immobilize or stabilize environmental contaminants whereas the phytoremediation is the use of plants removal of contaminants. Soil microorganisms which are associated with vetiver exhibited diversity among bacteria, fungi, microalgae, etc. Vetiver grass (Vetiver zizanioides) has been utilized for waste treatment activities in the soil and water polluted environment. All soil microbes share their survival and adaptation with vetiver. Thus, soil microbes associated with vetiver do not only produce nutrient sources for vetiver growth and development, but also induce plant growth hormones that affect vetiver directly. In addition, microorganisms could analyzed some organic pollutants.
