The effect of enzymes in fermentation biology
The effect of enzymes
Enzymes are specific biological catalysers, which accelerate or even make possible the biochemical reactions.
In the first step of biogas production - hydrolysis - enzymes split the materials in the substrate (cellulose, hemicellulose, pectins, starches, proteins, lipids) into substances that can cross cell membranes (sugars, amino acids, fatty acids). There are 2 enzyme groups at work here:
Only after this step can the bacteria involved in the biogas process perform the further steps of biogas production.
Enzymes support the methane generating process when using fibre-rich substrates.
Various enzyme types support the fibre and molecule breakdown processes in the hydrolysis phase
