• Resumen

  • The emergence of drug resistance, caused due the presence of pharmaceutical contaminant in the environment, highlights the critical need for pharmaceutical drugs management. Pharmaceutical drugs are sourced in wastewater as pharmaceutical industrial effluents, antibiotic misuse, and inappropriate disposal of expired pharmaceuticals, eventually ending up in sewage deposition. In this work, we aimed to degrade paracetamol (APAP) through the mycoremediation approach in laboratory scale. The isolated paracetamol degradation fungal strain, identified as Aspergillus niger KCAC efficiently degraded the drug into non-toxic metabolites. The results demonstrated that 99.6% degradation rate was achieved by Aspergillus niger KCAC. Unique, low-cost, eco-friendly bioformulation of the fungal isolate was prepared during the study using used vegetable cooking oil as substrate. The bioformulation showed extended shelf-life and can be used in future for large-scale application. Thus, this detailed investigation on paracetamol biodegradation may be useful in developing a wastewater treatment system effective against paracetamol-contaminated wastewater.
