Abstract
•The antibiotic effect on biogas production during anaerobic digestion was studied.•⩽280mg/L sulfamethazine and ⩽91mg/L tylosin did not inhibit biogas production.•⩽350mg/L ampicillin and ⩽6.4mg/L florfenicol did not inhibit biogas production.•Ampicillin, florfenicol, and tylosin were rapidly degraded within 5d of digestion.•Sulfamethazine and degradation products from florfenicol and tylosin were persistent.
The impacts of four common animal husbandry antibiotics (ampicillin, florfenicol, sulfamethazine, and tylosin) on anaerobic digestion (AD) treatment efficiency and the potential for antibiotic degradation during digestion were evaluated. Sulfamethazine and ampicillin exhibited no impact on total biogas production up to 280 and 350mg/L, respectively, although ampicillin inhibited biogas production rates during early stages of AD. Tylosin reduced biogas production by 10–38% between 130 and 913mg/L. Florfenicol reduced biogas by ∼5%, 40% and 75% at 6.4, 36 and 210mg/L, respectively. These antibiotic concentrations are higher than commonly seen for mixed feedlot manure, so impacts on full scale AD should be minimal. Antibiotic degradation products were found, confirming AD effectively degraded ampicillin, florfenicol, and tylosin, although some products were persistent throughout the process. Contamination of AD solid and liquid effluents with sulfamethazine and antibiotic transformation products from florfenicol and tylosin could present an environmental concern.
