Role and mechanism of rare earth oxides in alleviating ammonia inhibition and facilitating methanogenesis

Key Points

• Methanogenesis increases with rare earth oxides present, counteracting ammonia inhibition effectively.
• Increased methanogenic activity was observed with a notable improvement of approximately 30% in methane yield.
• Assessment using biochemical pathways and catalytic mechanism impact to demonstrate the efficacy of rare earth oxides.
• Highlights the necessity for further studies to translate lab results to field applications for biogas production.
