Mechanistic insights into promoted biogas production and reduced antibiotic resistance genes' risks of dry anaerobic digestion of organic wastes with biochar addition.

ABSTRACT: To explore the bioaugmentation mechanism of biogas-production promotion and risk reduction of antibiotic-resistance genes (ARGs) in the anerobic co-digestion of cattle manure and rice straw with biochar addition, the performances of digestion and productivity with different amounts of biochar additions (0, 1.25, 3.75 and 5 g·L⁻¹ slurry) were studied. The results indicated that, biochar addition could effectively promote biogas production, and the cumulative methane (CH₄) yields from the treatments with 3.75 g·L⁻¹ slurry and 5 g·L⁻¹ slurry biochar additions were18.7 times and 14.8 times of CK (0 g·L⁻¹ slurry), respectively. Combined with Fourier transform infrared spectroscopy (FTIR) analysis and high-throughput sequencing-based microbial community quantification, the methanogene
