Residual ciprofloxacin in chicken manure inhibits methane production in an anaerobic digestion system.

ABSTRACT: Anaerobic digestion (AD) is commonly used to dispose of laying hen manure. However, veterinary antibiotic residues present in chicken manure may affect the AD process. Here, the effects of three types of veterinary antibiotics commonly used in laying hen breeding on AD were explored. Manures containing antibiotics at two different concentrations were continuously added during AD for 5 days: amoxicillin (H_AMX: 145.06 mg/kg, L_AMX: 57.88 mg/kg), doxycycline (H_DOC: 183.61 mg/kg, L_DOC: 98.00 mg/kg), and ciprofloxacin (H_CIP: 96.34 mg/kg, L_CIP: 40.43 mg/kg). Compared with a control with no veterinary antibiotics, the amoxicillin and doxycycline groups presented no significant effects on biogas production, methane production, VFA co
