Industrial development may result in the increase of environmental risks. The enzymatic transformation of polluting compounds to less toxic or even innocuous products is an alternative to their complete removal. In this regard, a number of different redox enzymes are able to transform a wide variety of toxic pollutants, such as polynuclear aromatic hydrocarbons, phenols, azo dyes, heavy metals, etc. Here, novel information on chromate reductases, enzymes that carry out the reduction of highly toxic CrVI to the less toxic insoluble CrIII, is discussed. In addition, the properties and application of bacterial and eukaryotic proteins lignin-modifying enzymes, peroxidases and cytochromes useful in environmental enzymology is also discussed.
