Destruction of and the impact of chlortetracycline on biomethane production during anaerobic digestion of chicken manure.

Research was undertaken to ascertain the effect on biogas potential during the anaerobic digestion of chicken manure containing and chlortetracycline (antibiotic) from infected chicken flocks. is a pathogenic bacteria in chicken flocks that is usually treated with the broad-spectrum antibiotic, chlortetracycline.
