Bioremediation: A Sustainable Tool for Environmental Management of Oily Sludge

摘要

Advances in technology and industrialization, bring with them, their unpleasant partners, pollution anddegradation of the environment. The effects on the environment connected with industrial activitiesare mainly related to the production of industrial wastes. Because of problem associated with pollutanttreatment by conventional methods, such as chemical treatment, incineration or landfills, an alternativeapproach, bioremediation, or the use of organisms for the removal of contamination or pollutants hasbecome a popular option. Bioremediation is considered as one of the safer, cleaner, cost effective andenvironmental friendly technology for decontaminating sites which are contaminated with wide range ofpollutants. As microorganisms show wide range of mechanisms, there are still few mechanisms whichare not known, therefore, bioremediation is still considered as a developing technology. Thus, there is anurgent need for us to review and modify the available options for environmental clean-up. The objectiveof this paper is to conduct a comprehensive review on various indigenous microorganisms extractedfrom contaminated soil and capable of bioremediation of hydrocarbons present in the sludge.
