Influence of antibiotics on methane outcome during the anaerobic digestion process
| Feedstock | Antibiotic | Dosage | Methane production | References |
|---|---|---|---|---|
| Dewatered sludge | Roxithromycin | 0–1 mg L−1 | Reduced from 0.164 L per gVS to 0.151 L per gVS | Ni et al. (2020a) |
| Swine manure | Chlortetracycline | 0–0.5 g per kg TS | Reduced by up to 37.3% | Yin et al. (2016) |
| Swine manure | Oxytetracycline | Inhibited gas yield by 8.3–22.1% | Yin et al. (2016) | |
| Dewatered sludge | Sulphadimethoxine | 100 mg L−1 | Increased methane output by 39–52% | Zhi et al. (2019) |
| Dewatered sludge | Oxytetracycline | Enhanced methane output by 1–25% | Zhi et al. (2019) | |
| Cattle manure | Ceftiofur | 0.2–250 mg L−1 | Reduced methane output by 20% at dosage > 50 mg L−1 | Flores-Orozco et al. (2020) |
| Cattle manure | Chlortetracycline | 0.04–1.28 mg L−1 | Reduced methane output by 12–33% at concentration > 0.64 mg L−1 | Andriamanohiarisoamanana et al. (2020) |
| Cattle manure | Oxytetracycline | Reduced methane yield by 20–32% | Andriamanohiarisoamanana et al. (2020) |
The table demonstrates that the existence of most antibiotics can reduce the anaerobic digestion performance due to their inhibitory effect on microorganisms
