文摘
- •
Biochar promoted methanogenesis facing double stresses of high ammonium and acid.
- •
Methanosaeta was enriched around biochar particles in the early stage of digestion.
- •
Methanosarcina dominated in the later stage of digestion in tightly bound fraction.
- •
Fine biochar facilitated the production of organic acids.
- •
Biochar particle size was vital for cell accessibility and subsequent performance.
