With the advent of globalization and urbanization countries around the globe have disturbed the ecological balance in way that the earth has never seen before. Environmental pollution has been on the constant rise many folds in the past few decades owing to increased human activities on energy resources, excess use of chemicals in agricultural practices and rapid industrialization. These practices are posing various serious threats to environment and public health due to the nature of pollutants involved which are toxic in nature. These pollutants involves heavy metals, nuclear wastes, pesticides, herbicides, greenhouse gases and hydrocarbon etc. Hence, remediation of these affected sites is necessary, but the existing methods of remediation does involve chemicals which at the end again pose danger to the environment in other toxic forms. Due to this constrain in the remediation process the contaminant sites are difficult to be cleaned properly. Bioremediation has evolved as an environment friendly, reliable and cost effective method of treating contaminant sites. Bioremediation involves the use of microbial metabolism to remove these harmful pollutants from sites to make them usable again without any ill consequences on the environment. Bioremediation involves various technologies which includes biostimulation, bioaugmentation, bioaccumulation, biosorption, and phytoremediation. Bioremediation can either be carried out ex situ or in situ, depending on numerous factors, which include cost, site characteristics, nature and concentration of pollutants. This review attempts to provide descriptive information on the bioremediation, types of bioremediation and its scenario in Indian context.
