Which destabilizing outcome occurs when hydrogen sulfide concentration increases in anaerobic digester?

💡 Explanation

When hydrogen sulfide concentration increases, sulfur poisoning occurs because it inhibits enzymes crucial for methanogenic archaea, which are essential for converting organic matter into methane. Therefore, inhibiting methanogens activity results, rather than alternatives because VFAs requires different bacteria, nitrogen fixation requires nitrogen fixing processes, and cellulolysis uses hydrolysis.
