Resumen: "In this work, the white-rot fungus Pleurotus djamor was used for the first time to determine the degradation kinetics of the nonsteroidal anti-inflammatory drugs diclofenac, naproxen and, ketoprofen, either individually or in mixtures, in submerged cultures. Removal of 93% individual diclofenac and 99% diclofenac in mixtures with naproxen and ketoprofen at 6 h of incubation with the fungus was achieved. The elimination levels of naproxen and ketoprofen individually were 90% and 87%, respectively, after 48 h of incubation. However, the removal levels of these compounds in mixtures were 85% and 83%, respectively. On the other hand, during the degradation kinetics analysis, the enzymatic activities of laccases, manganese peroxidases, and lignin peroxidases were evaluated, yielding values of 3700, 270 and 31 U/L, respectively. Additionally, it was demonstrated that during the degradation of diclofenac or the three drugs mixed in the submerged cultures, the enzymatic activity of extracellular laccases expressed by P. djamor increased by 200% and 300%, respectively. The activity of manganese peroxides increased by 126% with diclofenac and 138% when the mixture of drugs was added to the cultures. On the other hand, lignin peroxidase only increased activity by 123% with the drug mixture.
