Bioremediation: A potential solution to reduce our footprint Industrialized societies are now tormented by several pollution problems that were largely unknown prior to WWII. Prominent among these problems is environmental pollution of xenobiotic synthetic chemicals that fail to be recycled by microorganism and may be biomagnified with destructive effects. Also, deforestation, land conversion, overhunting and the burning of fossil fuels are other human’s activities that impact negatively our ecosystem

Today Bioremediation has gained unparalleled importance in scientific fields. The term bioremediation very effectively describes its most important characteristic which is the use of living microorganisms for the improvement of the environment and maintaining a homeostasis in the ecosystem. It is used to clean up a vast range of hazardous waste from industries, farms, cities etc. These days the amount of pollutants and the variety of pollutants in the environment are increasing exponentially.

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

source of carbon and energy. A way to mitigate the effects of oil spills is bioremediation. 2.1 Bioremediation It is a process by which chemical substances are degraded by bacteria and other microorganisms. The use of these microorganisms has been successfully applied for the treatment of waste and wastewater in controlled systems. Several research studies have recently been performed to investigate the use of bioremediation for oil-spill cleanup in seawater, freshwater and terrestrial areas. The

Aluminium is the most abundant metal in the earth’s crust which occupies 8.8% of its weight and it is most commonly used in water supplies, medicines (Yavuz et al. 2004), explosives, construction of siding, aircrafts and motor vehicles and in food industry as cans, packaging materials, kitchen utensils and vessels (Tuzen and Soylak 2008). Consequently, the environmental exposure of aluminum to human and other animals is obviously possible. This metal ion causes Parkinson’s disease, Alzheimer’s

own way of degrading oil. Bioremediation is an option that offers the possibility to destroy or render harmless various contaminants using natural biological activity. As such, it uses relatively low-cost, low-technology techniques, which generally have a high public acceptance and can often be carried out on site Keeler, 2003). However, the time scales involved are relatively long, and the residual contaminant levels achievable may not always be appropriate. Bioremediation has been used at a number

Over the past ten years, the Institute of Gas Technology, now Gas Technology Institute (GTI), USA and others have conducted research on the bioremediation of organic contaminants in soil. Most of this work has been associated with remediation of former Manufactured Gas Plant (MGP) sites, soils from industrial areas and oil production areas have also been studied. The results have shown that: (1) organic contaminants are biodegraded by indigenous soil microorganisms to a concentration that no longer

Psychrophiles utilize a wide assortment of metabolic pathways, including photosynthesis, chemoautotrophy and heterotrophy and structure vigorous, various groups. The Cold-adjusted microorganisms assume a noteworthy part in supplement turn over and essential biomass creation in frosty biological systems and have vital applications in biotechnology (Erhard Bremer, 2012). In addition, exposed to the harsh elements
