Bacteria; An Efficient Bioremediator of Heavy Metals

Abstract

Commercialization and Indiscriminate growth of industrial sector has led down great impact not only on our living standard but also on environment. Indiscriminate release of heavy metals as industrial pollutant has been tremendously increased. The bio-availability of toxic heavy metals ions directs biomagnification that resulted in severe health hazards. Microorganism can offers attractive, eco-friendly and possible solution to this concern. Bacteria combat metal toxicity through adapted resistance mechanisms that can be exploited to minimize the alarming effects of heavy metals. Bioremediation through resistant bacteria serve as great temptation in modern research due to its promising results. This technology still needs more exploration in order to yield maximal results. Further research on different parameters of research design for bioremediation of heavy metals can led to innovation and even more sustainable model of pollution control. This review comprehensively highlights the sources, importance, consequences of heavy metals pollution. This review also described the underlying mechanisms of metal resistance by bacterial species to combat their devastating effects in terms of environmental pollution.
