Biogas fermentation
WebFermentation is an anaerobic process that breaks down the glucose within organic materials. It is a series of chemical reactions that convert sugars to alcohol or acid. Yeast or bacteria are added to the biomass material, which feed on the sugars to produce ethanol and carbon dioxide. WebBiogas production is a process known as methane fermentation, consisting of four stages of anaerobic decomposition. These four stages are hydrolysis, acidogenesis, …
