| Abstract: | Antibiotics have been abused in livestock as veterinary drug and feed additive. Their incomplete metabolization by animals resulted in heavy accumulation in livestock manure, and therefore they can pose a threat to the environment. In this study, the mechanism of three antibiotics (oxytetracycline (OTC), sulfadiazine (SDZ), enrofloxacin (ENR)) removal/biodegradation by Trametes versicolor pellets in air-pulse fluidized-bed reactor was explored, and the effects of wood immobilized T. versicolor on four antibiotics (OTC, SDZ, ENR and chloramphenicol (CAP)) removal in solid cow manures were evaluated. T. versicolor could remove OTC, SDZ, ENR through adsorption and biodegradation, with the removal efficiency at 92 % and 98 % in 21 h and 98 % after 68 h, respectively. The removal kinetics of those three antibiotics fitted well with the first-order kinetic model, with the removal constant k at -0. 238 h, -0. 102 h and -0. 023 h, respectively. T. versicolor could biodegrade those three antibiotics using laccase and cytochrome P450 system with the order SDZ ≈ OTC. |
