Abstract
Biogas is hydrogen or methane gas produced by fermentation from
biomass. The decomposition of methane biomass occurs with the participation of
three different bacteria. In the nutrient chain, the last bacteria feed on the
anterior bacteria. The first form is hydrolytic bacteria, the second is acid-forming
bacteria, the third is methane-forming bacteria. In the production of biogas, not
only bacteria belonging to the methanogenic class are used, but also all three
species. Biogas production does not exclude the release of methane into the
environment. Methane pollutes evaporation 21 times stronger than CO2 and
stores in the atmosphere for up to 12 years without decay. Methane reduction is
a measure to prevent global heat.
Key words:
biogas, anaerobic fermentation, droppings, biodegradation,
manure, compost, methane, aeration.
