ABSTRACT

Nowadays, global concern is for the removal of heavy metals, hydrocarbons, and radioactive wastes from soil and water. These are dangerous for the environment and human health. Removal of these contaminants from polluted soils and water is one of the major challenging tasks. The textile industry is spread worldwide and consumes more water. Therefore, water pollution by dyes is significantly increased and causes undesirable effects. Various methods and techniques are available for the clean-up of pollutants from water bodies. Nano-bioremediation is an emerging technology for the remediation of pollutants with the aid of biosynthetic nanoparticles. The application of biogenic nanoparticles for the removal of a wide range of pollutants is growing rapidly as they are non-toxic and easy to prepare using biological entities. This present chapter discusses the application of biogenic nanoparticles synthesized from yeast, fungi, bacteria, and plants as a nanocatalyst for the remediation of dyes from the aqueous system.
