ABSTRACT
The industrial revolution and rapidly escalating world population induced the environmental pollution which has become a significant predicament of the Earth. Numerous physical, chemical and biological methods are used to control pollution where each technique has both unique advantages and disadvantages. The biological methods for decontamination alternate costly and ineffective physicochemical methods. Laboratory level and commercially available GMOs are widely used since they have high potential of recovering and assimilating pollutants in enhanced rates and capacities. It has some disadvantages when they are released into the natural environment. Scientists make efforts to implement innovative studies to improve GMO as an environmental friendly bioagent in pollution control. This paper reviews the existing literature of applying GMO for pollution control, risks and limitations, to formulate a compendium of present and past developments, improving the state of knowledge. The research priorities and future challenges that will support the development of effective GMO in the pollution control with multi-prong strategies were discussed.
