Abstract

Abstract

En 中文
• Nickel regulates carbon distribution in autotrophic biomethanation. • Nickel limitation suppresses methane formation and microbial growth. • Excess nickel destabilizes thermophilic hydrogenotrophic methanation. • Carrier media structure affects metabolic recovery and reactor resilience. • Optimal Ni (1.36 mg/L) supported stable methane production.
