Abstract

Pollutant removal from industrial effluents is a big challenge for industries. These pollutants pose a great risk to the environment. Nanotechnology can reduce the expenditure made by industries to mitigate these pollutants through the production of eco-friendly nanomaterials. Nanomaterials are gaining attention due to their enhanced physical, chemical, and mechanical properties. Using microorganisms in the production of nanoparticles provides an even greater boost to green biotechnology as an emerging field of nanotechnology for sustainable production and cost reduction. In this mini review, efforts are made to discuss the various aspects of industrial effluent bioremediation through microbial nanotechnology integration. The use of enzymes with nanotechnology has produced higher activity and reusability of enzymes. This mini review also provides an insight into the advantages of the use of nanotechnology as compared to conventional practices in these areas.

Highlights

Water is essential for the continuation of life on earth, so the removal of pollution from water is just as crucial
The synthesized nanoparticles were able to remove more than 90% of heavy metals [Pb (II), Ni (II), Cu (II), and Zn (II)] from wastewater with a regeneration capability of up to five cycles
The integration of microorganisms and enzymes with nanotechnology has provided a greener approach toward the management of industrial effluents (Dixit et al, 2020; Zhang et al, 2020)

Summary

Introduction

Water is essential for the continuation of life on earth, so the removal of pollution from water is just as crucial. The use of microorganisms and enzyme-assisted green nanotechnology to remove and valorize waste materials is discussed. Nanoparticles have been widely used as adsorbents to remove harmful contaminants from industrial wastewater. Superparamagnetic composite of iron oxide nanoparticles with activated carbon was found to be suitable to remove Cr(VI) from wastewater.
