Page: Acetogenesis
Acetogenesis the carbonic acids are converted to acetate, H{}2 and CO{}2. Just these substances can be changed directly into methane by methanogenic bacteria. This process is also called "anaerobic oxidation", because electrons in the form of H{}2 are released. The releasing of butyric ...

AMMONIA RESULTS AT HYDROLYSIS OF AMINO ACIDS AND AFFECT HARMFUL IN LOW QUANTITIES BUT AS AMMONIA IT ATTENDS AS NUTRIENT RESOURCE.Ammonia and ammonium are dependent on each other concerning their phvalue. This dissociation balance is shown in Figure 13. \!ammoniumammoniak.JPG\!Figure 13:  dissociation balance ...

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 ...

most common method biogas is combusted in a gas engine. The rotary motion of the engine powers the generator, which is generating electrical power. It is needful to apply an inverter and a transformator after the generator to feed the electrical power into the public power network. The waste ...

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: Further Inhibitors
Bacteria use some heavy metals and micronutrients as nutrients, but they have an inhibiting effect if their concentration is too high. The most important inhibitors and their harmful concentrations are shown in Figure 15. Figure 15: Inhibitors and harmful concentrations. !further inhibitors.JPG

amount of biogas in a biogas plant depends on the composition of the applied substrate. Substrate has an effect on the quality of biogas and the methane yield. It is ASSIGNED ON the composition of the contingent of fat, proteins and carbon hydrates. Fat indicates regarding the mass more methane than ...

Page: Hydrosulfide
Sulfur plays an important role, because it is an important mineral compound for methanogenic bacteria and heavy metals can be bond by formed sulfide ions on the one hand. On the other hand, the degradation process can be inhibited because of higher concentrations ...

combination of the substrate has a heavy effect on fermentation, because out of the used substrate as much methane as possible should be produced. Bacteria, especially methane bacteria, need micronutrients and nutrients for growing (shown in Figure 11). For an optimal biogas yield ...
