According to the Gale Encyclopedia of Science (2008), bioremediation is any process that purifies an environment polluted by organic or inorganic contaminants with the utilization of microorganisms or other such creatures. Intensive industrialization and inadequate disposal of organic and inorganic compounds have brought about long-term persistent sources of contamination of our environment. This is a major environmental, policy and health issue facing numerous countries today. Current methods for remediation of polluted environments incorporate chemical and physical remediation,…show more content…
As opposed to depending on organisms and their flexibility in achieving bioremediation of polluted environments, plants either alone or in combination with microorganisms have been used for this reason. The idea of utilizing plants to help with the cleanup of contaminated ecosystems is not new. About 300 years ago, plants were proposed for utilization in the treatment of waste water. Vegetation-based bioremediation shows potential for aggregating, immobilizing and changing a low level of persistent contaminants (Rayu et al., 2012). The phytoremediation approach has several advantages including decreased expense, public acceptance and in particular the capacity of simultaneous evacuation of organic and inorganic contaminants. Phytoremediation might additionally be utilized as a last cleaning venture in combination with other microorganism driven treatment technologies, a technique called microbe-assisted phytoremediation. Regardless of its positive aspects, the commercial application of phytoremediation is slow. According to experts (Rayu et al., 2012), this is because of the following limitations: (1) lack of or slow development of plants at polluted locations which results into low viability of phytoremediation, (2) the proficiency is constrained by the diminished capacity of plants to enter in the soil through their root system and access the hazardous wastes, (3) the time needed for viable phytoremediation is frequently long with
