Which mechanism inhibits methane production when anaerobic digester temperature fluctuates excessively?

💡 Explanation

When temperature fluctuates, enzyme denaturation occurs because bonds maintaining protein structure are broken, reducing activity in hydrolysis and acidogenesis stages leading to inhibited methanogenesis. Therefore, a reduced hydrolysis rate results, rather than others which would need specific substrate/product imbalances or disruptions to pH balance.
