Modellierung der anaeroben Bioabfallvergärung unter Berücksichtigung von syntrophen Propionat‐oxidierenden BakterienModeling of Anaerobic Digestion Considering Biowaste by Syntrophic Propionate‐Oxidizing Bacteria.

Abstract: Anaerobic digestion of biowaste allows a sustainable production of bioenergy and reduces environmental burden. The anaerobic digestion phase was modeled with Anaerobic Digestion Model No. 1 (ADM1), which was extended to include three genera of propionate‐oxidizing bacteria and two routes of propionate degradation, namely methyl‐malonyl CoA and C6‐dismutation pathway. Kinetic parameters for anaerobic propionate oxidation were determined with defined tricultures of the three propionate‐oxidizing genera together with hydrogenotrophic and acetotrophic methanogens and implemented into ADM1, resulting in the improved model ADM1xpro.
