Emerging pollutants can reach the environment through the sludge of Wastewater Treatment Plants. In this work, the use of Trametes versicolor in biopiles at lab-scale was studied, evaluating its capacity to remove the most hydrophobic Pharmaceuticals and assessing the evolution of the biopiles microbial communities. The total removal of drugs at real concentrations from sewage sludge was assessed for non-inoculated and fungal inoculated biopiles, testing if the re-inoculation of the biopiles after 22 days of treatment would improve the removal yields. It was found that 2 out of the 15 initially detected pharmaceuticals were totally degraded after 22 days, and re-inoculated fungal biopiles achieved higher removal rates than non-re-inoculated fungal biopiles for single compounds and for all the drugs simultaneously: 66.45% and 49.18% re-inoculated and non-re-inoculated biopiles, respectively. Finally, the study of the bacterial and fungal communities revealed that fungal inoculated and non-inoculated biopiles evolved to similar communities adapted to the presence of those drugs.
新兴污染物可以通过污水处理厂的污泥进入环境。在这项工作中，研究了在实验室规模的生物堆中使用彩绒革盖菌来去除最疏水性药物，并评估生物堆微生物群落的演变。评估了未接种和真菌接种生物堆在实际浓度下从污水污泥中去除药物的总去除率，测试了在处理 22 天后重新接种生物堆是否会提高去除率。结果发现，在 22 天后，最初检测到的 15 种药物中有 2 种被完全降解，对于单一化合物和所有药物同时，重新接种真菌生物堆的去除率高于未重新接种真菌生物堆：分别为 66.45%和 49.18%。最后，对细菌和真菌群落的研究表明，真菌接种和未接种生物堆演变成适应这些药物存在的相似群落。
