Acetogenesis continues and it entails the further breakdown

Acetogenesis continues and it entails the further breakdown of simple molecules created in the acidogenesis stage by acetogens. The main products of acetogenesis are “acetic acid, carbon dioxide, and hydrogen” (Khopkar, 2004). This stage is followed by methanogenesis (the final stage in the production of methane), where methane alongside water and carbon dioxide is produced. This comes by when methanogens act on all the intermediate products produced in the preceding stages. Methagonesis is sensitive to both acidic and basic conditions. Therefore, a pH of 6.5 to 8 is desirable. The residue (indigestible material) that cannot be fed on by the microbes together with the dead bacteria remains, make up the digestate (Khopkar, 2004).
