How Anaerobic Digestion Works

1. Hydrolysis

In this initial stage, complex organic matter such as carbohydrates, proteins, and lipids are broken down into simpler compounds by hydrolytic enzymes. This process converts complex organic substances into soluble compounds that can be easily utilized by microorganisms.

2. Acidogenesis

During this stage, acidogenic bacteria metabolize the products of hydrolysis, converting them into volatile fatty acids (VFAs), alcohols, and other intermediate compounds. These acidogenic reactions result in the production of organic acids.

3. Acetogenesis

Acetogenic bacteria further process the products of acidogenesis, primarily the VFAs, and convert them into acetic acid, carbon dioxide, and hydrogen. Acetogenesis is a crucial step that generates the precursors needed for the subsequent methane production.

4. Methanogenesis

The final stage involves methanogenic archaea that utilize the intermediates produced in the previous stages to produce methane gas (CH4) through a series of biochemical reactions. This methane-rich biogas is the desired end product of anaerobic digestion and can be utilized as a renewable energy source.
