Page: Acidification
fragments of the hydrolysis are metabolized by facultative and fastidious anaerobes to carboxylic acids like acetic acid, propionic acid, butyric acid, valeric acid and hexane acid. In addition, they are metabolized to alcohol, hydrogen (H{}2) and carbon dioxide (CO{}2). There is a poor ...

Page: Biogas Production
HISTORY{} In 1776 the Italian physicist and nature scientist Alessandro Volta discovered the appearance of methane at the anaerobic degradation of organic matter by connecting marsh gas in the mud of lakes and making combustion experiments. In 1821 the English physicist Michael Faraday identified methane ...

Page: Development of biogas
conversion of biomass to biogas can be classified into four phases. In every phase there are specific microorganisms, which are working in interaction among themselves to metabolize the organic matter to build gas. The phases of biogas development are shown in Figure 3. !composed, particular substrates.JPG

Page: Hydrolysis
Complex and long chained chemical bonds like carbohydrates, proteins and fats are degraded to smaller organic compounds like monosaccharides,  amino acids and glycerin by hydrolysis. The responsible bacteria release enzymes, which brake down the material on a biochemical path ...

Page: Methanogenesis
last but most important step of generating biogas. Methane can be metabolized out of acetic acid (CH{}3{}COOH), H{}2 and CO{}2, methanol of methylene (CH{}3{}NH{}3). Responsible microorganisms are methanogenic bacteria. They are strictly ...

Page: New developments
biogas production several starting points of new developments can be chased: • Speeding up hydrolysis. On one hand the influence of sonication in consideration of a fast digestion of biomass is determined, on the other hand the adoption of high pressures and temperatures. • Addition of enzyme supplement ...
