ABSTRACT
Rapid industrialization, unbalanced growth, development and race for advanced arms and ammunitions all over the globe have resulted in generation of unwanted things in the forms of chemicals, heavy metals and xenobiotics. Excessive presence of such undesirable materials in the environment results in poor and imbalanced ecosystem. This review focuses on contaminated ecosystems and their bioremediation as well as influence of different microorganisms and their activity which supports removal of pollutants from environment. Many studies are devoted to bioremediation because interpretation of microorganism's activity in polluted ecosystems is very difficult. For that reason, there is still an ongoing search for efficient and potential strains that can remove and/or detoxify many hazardous contaminants at the same time. Therefore, the main goal of the review is to present the current knowledge regarding the problems associated with the use of various groups of rhizospheric microorganisms that are able to assist in treatment processes.
