Abstract: In this modern era, the environment is being contaminated with toxic pollutants as a result
of anthropogenic activities. To overcome the harmful effects of pollutants, scientists have developed
ideas and technologies. Biotechnology provides a green approach for decontaminating the environment,
i.e., bioremediation. Several organisms have been explored for their enzymes. Enzymes belonging
to various classes are useful for degrading, transforming, or removal of pollutants. Oxidoreductases
produced by different plants, bacteria, and fungi are useful for deterioration of toxic pollutants,
like compounds having aroma, called aromatic compounds (benzene, chlorine, phenols, phenanthrene,
etc.), PAHs (Polyaromatic Hydrocarbons), various dyes, etc. Oxidoreductases are further
classified as laccases, peroxidases, and oxygenases. All three classes have proven to be efficacious in
the field of bioremediation. Microorganism strains have also been genetically engineered for the production
of enzymes. Oxidoreductases can be used to remove pollutants from industrial waste. This
review has classified all the species that produce oxidoreductase enzymes, their mechanism of action,
and the pollutants that have been removed by using oxidoreductases.
