Resumen:

The constantly increasing world population combined with the intensification of industrial and agricultural activities have caused the accumulation of pollutants in the soil, water, and air. Emerging contaminants (ECs), such as pharmaceutical and personal care products, are in many countries unregulated and could affect human and animal health, causing endocrine disruption, physiological changes, or microbial resistance. Therefore, several studies have focused on understanding the effects of these pollutants on health and the development of technologies for their remediation, including physicochemical methods, chemical oxidation, and bioremediation. Bioremediation is eco-friendly, includes the use of microorganisms or their enzymes, and could be applied in situ and ex situ. However, the disadvantages are that the processes are slow and depend on the pollutant?s environmental conditions and properties. Interestingly, different studies indicate the potential use of laccases to degrade or oxidize ECs based on their biocatalytic properties. Although bacterial laccases are considered to have low redox potential, when compared with fungal laccases, these enzymes have aroused interest due to their high tolerance to inhibitors, such as high halide concentrations and alkaline media, which makes them potentially effective for the degradation of ECs. This chapter highlights the properties of bacterial laccases and their possible utility use in the degradation or transformation of ECs, which are constantly accumulating and disturbing the balance of ecological niches. © 2024 Elsevier Inc.
