Microbial paracetamol degradation involves a high diversity of novel amidase enzyme candidates

Pharmaceuticals are relatively new to nature and often not completely removed in wastewater treatment plants (WWTPs). Consequently, these micropollutants end up in water bodies all around the world posing a great environmental risk. One exception to this recalcitrant conversion is paracetamol, whose full degradation has been linked to several microorganisms. However, the genes and corresponding proteins involved in microbial paracetamol degradation are still elusive. In this study, we aimed at improving our knowledge of the microbial paracetamol degradation pathway.
