Methanogenic Microbial Populations in Anaerobic Digesters
Wiki Article
Anaerobic digesters rely on the intricate interplay of various microbial species to transform organic matter into valuable biogas. At the heart of this process lie methanogenic archaea, a group of microorganisms responsible for producing methane, the primary component of biogas. These entities thrive in extensively anaerobic environments, where organic compounds are broken down through a series of biochemical transformations. Methanogens exhibit remarkable variability in their metabolic pathways and preferences for substrates.
