Understanding the Role of Bacteria in Biogas Fermentation

Bacteria play a pivotal role in the biogas production process through anaerobic fermentation. These microscopic organisms break down organic matter such as plant biomass and animal waste in the absence of oxygen, releasing methane and carbon dioxide as byproducts. Different bacterial species contribute in distinct stages of the fermentation cycle.

For example, hydrolytic bacteria initiate the process by disintegrating complex organic molecules into simpler compounds. Subsequently, acidogenic bacteria modify these compounds into organic acids. Methanogenic bacteria, the final players in the chain, utilize these acids to generate methane gas. The efficiency and rate of biogas generation are heavily influenced by the diversity and activity of these bacterial communities.
