BIOREMEDIATION OF CADMIUM

Environmental pollution caused by heavy metals has received increasing attention worldwide because of their recalcitrant and tenacious nature which leads to severe threat to environment superiority and life of both plants and animals, causing life threatening diseases in humans. Bioremediation is measured as one of the safer, cleaner, cost operative and environmental friendly technology for decontaminating sites which are contaminated with extensive range of pollutants which is due to the unawareness concerning production, use and disposal of hazardous materials. It uses numerous agents such as bacteria, yeast, fungi, algae and higher plants as main tools in treating oil spills and heavy metals existing in the environment. Arrival of lethal substantial metals in the earth by the various sources mainly by industrial activities present risky impacts to sea- going and earthbound living beings and furthermore to human life. Bioremediation is a process that debases, separate and expel contaminants from soil and water. It is a characteristic procedure which depends on microscopic organisms, parasites, green growth to change the contaminants present in condition. This review discusses the sources, techniques like situ and ex situ bioremediation and microorganisms utilized in bioremediation forms which corrupts contaminants present in condition and factors influencing the bioremediation. Complete pulverization of target poisons is conceivable by bioremediation technique.
