Abstract
The individual and combined effect of cefazolin (CFZ) and oxytetracycline (OTC) on thermophilic anaerobic digestion (55 °C) of dairy manure in batch digesters was investigated. Methane productions from the concentrations tested (30, 60 and 90 mg L−1) were compared with no-antibiotic control. CFZ concentrations showed no inhibition (P > 0.05) for methane production. The individual OTC and combined CFZ and OTC at concentrations of 30, 60 and 90 mg L−1 represented 79.1%, 70.3%, 68.6% (P < 0.05) and 88.5%, 82.7%, 70.3% (P < 0.05) respectively, of the control values. The high CH4 production, optimal pH and VFA data during digestion indicated the process stability and treatment efficiency.
