Human activities have increased pressure on the natural resources and become the source of a myriad of pollutants. Recent advancing in biotechnology, bioremediation has become one of the most rapidly developing fields of environmental restoration, utilizing microorganisms to reduce the concentration and toxicity of various chemical pollutants, such as organic and inorganic compounds, industrial solvents and pesticides etc. Currently, extensive research is being focused on finding an optimal microbial biomass that would be as cheap as possible for the removal of contaminating products from large volume of polluted area. Bioremediation is emerging as an effective and attractive management tool to treat and recover the environment, in an ecofriendly manner. Bioremediation has been used at a number of sites worldwide, with varying degrees of success. Bioremediation, both in situ and ex situ have also enjoyed strong scientific growth, in part due to the increased use of natural attenuation, since most natural attenuation is due to biodegradation. Bioremediation technology, which leads to degradation of pollutants, may be a lucrative as well as environmentally friendly alternative.
