Role of Nanotechnology in Microbial mediated Remediation

Abstract

Abstract Man-made pollution and pollutants are increasing day by day which has prompted alarming health issues and a declining availability of clean drinking water. Xenobiotic compounds from the waste of industries aggregate in agricultural soils and penetrates in the food chain. Thus, imposes a negative influence on the natural ecosystem and eventually impacts on human. The limitations of conventional methods used in remediation to get rid of the contaminants have given rise to trial nanotechnological aids for environmental clean-up by various researchers. The use of nanoparticles produced by microorganisms with the aid of nano biotechnology is known as nano bioremediation. This substitute for developing nanoparticles is an eco-compatible, environment-affable and cost-efficient method to eliminate the contaminants. Nanoparticles have shown their effectiveness over bulk materials as they confer easy handling, large surface area, economic viability, higher reactivity, and hence better performance. Microorganisms like bacteria, fungi, yeast, actinomycetes, and algae are exploited as a “biofactory” for the nanoparticle’s synthesis such as cadmium sulfide iron, silver, gold, platinum, titanium, titanium dioxide, palladium, magnetite, etc for the conversion and detoxification of the contaminants. Microbes have secured remarkable attentiveness as they possess the potency to synthesize nanoparticles in varying sizes, shapes and compositions with distinct physicochemical features for the elimination of heavy metals, organic, inorganic contaminants, organochlorines, dyes in soil and water treatment. Developments withinside the subject of nanoparticle biosynthesis will raise the commercial economic system through producing inexperienced energy. This manuscript emphasizes the importance and mechanism of environmental remediation of pollutants by microbe-driven nanoparticles.
