The purpose of this study is to establish a novel management of dairy manure by anaerobic digestion for ensuring the safety. We assumed the manure from dairy cows injected with veterinary antibiotics, and focused on the survival of antibiotic resistant bacteria during anaerobic digestion, and electrochemical inactivation of antibiotic resistant bacteria in anaerobically digested slurry. Results with manure samples from three different farms showed a similar trend that numbers of antibiotic-resistant bacteria decreased after the anaerobic digestion except for specific antibiotics. The electrochemical disinfection process decreased numbers of antibiotic-resistant bacteria in the anaerobically digested slurry. The result indicates that the batch mesophilic anaerobic digestion and electrochemical process can reduce relative risks of antibiotic-resistance bacteria in livestock manure.

本研究的目的是建立一种新的奶牛粪便厌氧消化管理方法，以确保其安全性。假设奶牛粪便注射了兽用抗生素，重点研究了厌氧消化过程中耐药菌的存活情况，以及厌氧消化浆料中耐药菌的电化学失活情况。结果表明，除特定抗生素外，3个不同猪场粪便样品经厌氧消化后耐药菌数量均呈下降趋势。电化学消毒可降低厌氧消化浆液中耐药菌的数量。结果表明，间歇式中温厌氧消化和电化学处理可降低畜禽粪便中耐药菌的相对风险。
