Biodegradation prospective of microbes

The exponential growth of the human population has led to the accumulation of huge amounts of non-degradable waste materials across our planet. Living conditions in the biosphere are therefore changing dramatically, in such a way that the presence of non biodegradable residues is affecting the potential survival of many species. The present interest in hydrocarbon biodegradation is motivated in large part by their presence as environmental pollutants. Bioremediation has proven to be an alternative to diminish the effects caused by hydrocarbon pollution of soil and water, using the metabolic capacities of microorganisms that can use hydrocarbons as source of carbon and energy, or that can modify them by co metabolism. The bacteria are well-known for their metabolic diversity and this variety is the fact that many bio-hazardous or relentless anthropogenic chemical compounds are degraded by microbial activities. This review paper highlights the role of various microbes and their derivatives in degradation of hazardous substances from the environment.
