Hydrolysis (degradation of polymers)<br>2. Acidogenesis (the formation of volatile fatty acids - low molecular carboxylic acids)<br>3. Acetogenesis (the formation of acetate, CO2 and H2)<br>4. Methanogenesis (from acetete -> CO2 and CH4 is formed, from CO2 and H2 -> CH4 is formed, methanogenesis from acetate and CO2+H2 has to run simultaneously for the proces to be stable) <br><br>The last step is the reason why there will be always some CO2 in biogas. Each of this steps is carried out by different groups of microorganisms.<br><br>So the initial biochemical sources of biogas are carbohydrates, proteins, fats etc. In the long run, any substance that can be converted intermediately either to dissolved CO2 and H2 or to acetate is appropriate for biogas production.<br><br>BR from Slovenia, Gasan<o:p></o:p></p></div><div><p class=MsoNormal> <o:p></o:p></p></div><div><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#990033'>Ilja Gasan OSOJNIK ČRNIVEC, </span></b><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>L05 - Laboratory for Environmental Sciences and Engineering</span> <o:p></o:p></p><div><p class=MsoNormal> <o:p></o:p></p></div><p style='margin:0in;margin-bottom:.0001pt'><span style='font-size:9.0pt;font-family:"Arial","sans-serif"'><img width=380 height=42 id="_x0000_i1025" src="cid:image001.jpg@01CBE86E.966D6770" alt="KI+letokemije.jpg"></span><o:p></o:p></p><p style='margin:0in;margin-bottom:.0001pt'><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'> </span><o:p></o:p></p><p style='margin:0in;margin-bottom:.0001pt'><span style='font-size:9.0pt;font-family:"Arial","sans-serif"'>National Institute of Chemistry</span><o:p></o:p></p><p style='margin:0in;margin-bottom:.0001pt'><span style='font-size:9.0pt;font-family:"Arial","sans-serif"'>Hajdrihova 19</span><o:p></o:p></p><p style='margin:0in;margin-bottom:.0001pt'><span style='font-size:9.0pt;font-family:"Arial","sans-serif"'>SI-1001 Ljubljana</span><o:p></o:p></p><p style='margin:0in;margin-bottom:.0001pt'> <o:p></o:p></p><p style='margin:0in;margin-bottom:.0001pt'><span style='font-size:9.0pt;font-family:"Arial","sans-serif"'>Tel.: (01) 47 60 239</span><o:p></o:p></p><p style='margin:0in;margin-bottom:.0001pt'><span style='font-size:9.0pt;font-family:"Arial","sans-serif"'> (01) 47 60 200</span><o:p></o:p></p><p style='margin:0in;margin-bottom:.0001pt'><span style='font-size:9.0pt;font-family:"Arial","sans-serif"'>Fax: (01) 47 60 300</span><o:p></o:p></p><p style='margin:0in;margin-bottom:.0001pt'> <o:p></o:p></p><p style='margin:0in;margin-bottom:.0001pt'><span style='font-size:9.0pt;font-family:"Arial","sans-serif"'><a href="http://www.ki.si/en" target="_blank">www.ki.si/en</a></span><o:p></o:p></p><p style='margin:0in;margin-bottom:.0001pt'><span style='font-size:9.0pt;font-family:"Arial","sans-serif"'> </span><o:p></o:p></p><p style='margin:0in;margin-bottom:.0001pt;text-align:justify'><span style='font-size:7.5pt;font-family:"Arial","sans-serif"'>The National Institute of Chemistry is a public research institution engaged in public service, science, research and development activities.
