Abstract
The
ever-increasing population growth and industrialization have stemmed the
genesis of several environmentally related contaminants of emerging concern.
Numerous of them influence the living ecosystem, including pharmaceutically
bioactive residues, antibiotics, pesticide-based polluting agents,
industrial-based synthetic dyes, etc. Indeed, several approaches, e.g.,
chemical and physical treatments and their possible combinations, have been
proposed, established, and executed to treat and remove environmental
pollutants from numerous matrices. However, the existing approaches are
becoming inefficient due to the growing quantity and complex nature of
environmental contaminants. Therefore, more effective and suitable measures are
needed to sustain the green environment by remediating and mitigating the
hazards of emerging concerns associated with environmentally related
pollutants. Among other recent approaches, microbial biodiversity,
bio-mitigation assessment, and removal of current pollution load using robust
materials are of supreme interest with evident merits. In addition,
microorganisms have an enormous capacity to adapt and survive in divergent
environments and, once established, produce unique biocatalytic molecules that
break down and transform the contaminating agents, thus making it possible to
revive the polluted matrices. Likewise, nanozymes are nanostructured materials
with enzyme-like activities that effectively catalyze the breakdown of
contaminating agents and, thus, are other suitable candidates to upgrade modern
bioremediation practices. This review thoroughly examines the most recent
developments in novel bio-mitigation and nanozyme-based approaches. Finally, we
highlight their current challenges to provide a perspective on potential future
research directions.
