Comments Methanogenic degradation is the least exergonic process when compared to aerobic degradation or the alternative anaerobic respirations. Conversion of hexose to methane and carbon dioxide releases only 15% of the energy that would be available in aerobic degradation, C6H12O6+6O2>>6CO2+6H2O (Change of Gibbs free energy=-2,870 kJ/mol) C6H12O6>>3CO2+3CH4 (Change of Gibbs free energy=-390 kJ/mol)
