Combined lysine and cobalt supplementation improves semi-thermophilic anaerobic digestion performance with enhanced Methanosarcina-associated methylotrophic potential.
Protein-rich food waste challenges anaerobic digestion (AD) through rapid acidification and chronic ammonia stress. Semi-thermophilic AD (STAD, 41-49℃) offers a promising balance between mesophilic stability and thermophilic conversion efficiency, but further improvement may depend on strengthening methylotrophic metha...
