Anoxygenic Phototrophic Sulfur Bacteria and Their Application in Purification of Biogas

Popis výsledku v původním jazyce

Biogas represents one of the possible renewable resource of energy. It is produced by the breakdown of biodegradable waste. This process involves anaerobic microorganisms. One of the biggest problem of biogas is that raw biogas contains, besides useful methane, other unfavorable gases, such as carbon dioxide and hydrogen sulfide (typical composition: 50–70 % methane, 20–40 % carbon dioxide, and other gases (10–30 %), including hydrogen sulfide). Current physical-chemical methods of purification of biogas are usually ineffective and expensive. Therefore it is necessary to search for new methods of extracting pure methane. Anoxygenic phototrophic bacteria, belonging to families, Chlorobiaceae (green sulfur bacteria, GSB) and Chromatiaceae (purple sulfur bacteria, PSB). These microorganisms use reduced sulfur compounds including toxic hydrogen sulfide as an electron donors and carbon dioxide in the process of anoxygenic photosynthesis. Reduced sulfur is oxidized to elemental sulfur and accumulated outside of the cells (in GSB) or inside them (in PSB).
