由于抗生素不能被完全吸收而大部分随禽畜粪便进入环境将严重威胁生态环境及人类健康,探讨了高温堆肥去除鸡粪中氟喹诺酮类(Fluoroquinolones, FQs)抗生素(诺氟沙星、环丙沙星、洛美沙星、恩诺沙星、沙拉沙星)的可行性以及接种外源耐高温菌对去除 FQs的影响。结果表明:高温堆肥可去除鸡粪中48.4%~77.1%的 FQs,且 FQs 的降解在堆肥初期(0~14 d)较快;堆肥中 FQs 的降解可用一级动力学方程进行拟合,降解速率与鸡粪中 FQs的初始浓度正相关;接种外源耐高温菌种后FQs 的去除率为60.3%~76.4%,比未接种时提高了3.3%~7.2%,且诺氟沙星和洛美沙星的去除率显著提高。鉴于高温堆肥未能实现畜禽粪便中残留 FQs...

Fluoroquinolones(FQs), widely used in livestock and poultry breeding industry, may pose a serious threat to ecological environ—ment and human health after entering the environment via livestock manures. In the present study, we assessed the effects of high temperature composting and high temperature— resistant bacterium inoculation on the removal of FQs including norfloxacin, ciprofloxacin, lomefloxacin, enrofloxacin, and sarafloxacin. High temperature composting had a high potential to remove FQs in chicken manures, with relatively high degr...
