Explanation of the fermentation process
During the fermentation process, biomass is being degraded by a large number of microorganism populations in an oxygen free environment (anaerobic). During this process the bio-gas is formed.The fermentation process is a delicate one that can be easily disturbed. The process consists of 4 phases, in which a series of complex metabolic processes take place;
• Hydrolysis
• Fermentation (acidogenesis)
• Acetogenesis
• Methanogenesis
We distinguish mesophilic processes (temperatures between 35 and 37°C as well as thermophilic processes (55°C). In addition, we distinguish wet and dry fermentation.
