高温堆肥对鸡粪中氟喹诺酮类抗生素的去除
Effect of High Temperature Composting on Removal of Fluoroquinolones in Chicken Manures
摘要
Abstract
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 degradation rates at the early stage of composting(0~14 d). The degradation process of FQs by composting fitted the first order kinetic equation, indicating that FQs degradation rates were positively related to initial concentrations of FQs in chicken manures. Inoculating high temperature resistant bacteria increased the removal rates of FQs(norfloxacin, ciprofloxacin, lomefloxacin, enrofloxacin and sarafloxacin)by 3.3~7.2 percentage points, as compared to the non—inoculating control, with significant rises only for norfloxacin and lomefloxacin. Further studies on composting processes and bacterial inoculation methods are necessary to improve FQs removal rates in chicken manures.关键词
