Anaerobic Digesters: Methane Formation

Anaerobic Digesters: Methane Formation. The inter-microbial distances influence the biodegradation rates and specific growth in the formation of Methane. The microorganisms that form methane are physiological. They can grow only with a few specific substrates, such as H2 and CO2, formate, methanol, and acetate, and they, therefore, depend on others. Therefore, a syntrophic relationship is…
