15 Microbial oxidative enzymes in wastewater treatment: mechanisms and applications
-
Naresh Singhal
Abstract
Wastewater treatment systems lie at the interface of human society and the environment, ensuring that the treated water is safe for reuse or discharge. Microbial enzymes play a critical role in destroying water pollutants. This chapter covers the various types of oxidative enzymes (e.g., catalase-peroxidases, laccases, and cytochrome P450s) involved in transforming common wastewater pollutants, including organic micropollutants and dyes. We also document the challenges in implementing microbial oxidative enzyme-based treatment technologies, including limitations in enzyme stability and maintaining required operational conditions and explore potential strategy to overcome these constraints using enzyme immobilization and oxygen perturbation. In summary, microbial oxidative enzymes provide a highly effective, ecofriendly and sustainable solution for wastewater treatment and bioremediation.
