| Sumario: | <p id="p1">According to the analysis of material metabolic pathway, mutual symbiotic flora, and energy cooperative sharing, the paper proposed that the ideal anaerobic digestion metabolism process of hydrogen production followed by methane production coincided with the mutual symbiotic and synergistic mechanism. (1) Hydrogen, carbon dioxide, and acetate acid are the important intermediates in the process of anaerobic digestion for co-production of methane and hydrogen. (2) Hydrogen-producing acetogenic, bacteria and hydrogen-consuming methanogenic bacteria undergo mutual coupling to become the anaerobic symbiotic compact, sharing organic material degradation and contributing chemical energy (15 kJ/mol). (3) From the point of view of adenosine triphosphate (ATP) energetics, we explain the phenomenon of low energy dissipations of anaerobic digestion, which is about 20 kJ/mol of energy requirements for symbiotic community survival. The viewpoint of mutual symbiosis was supported by the typical case of mutual symbiotic community in the 1960s and H<sub>2</sub> hypothesis in the 1970s’ which also verified the optimal energy conversion efficiency of co-production of hydrogen and methane.</p> |
