dc.description.abstract | Dynamic reaction diffusion models were used to analyze the consequences of aggregation for syntrophic reactions in methanogenic ecosystems. Flocs from a whey digestor were used to measure all model parameters under the in situ conditions of a particular defined biological system. Fermentation simulations without adjustable parameters could precisely predict the kinetics of H 2 gas production of digestor flocs during syntrophic methanogenesis from ethanol. The results demonstrated a kinetic compartmentalization of H 2 metabolism inside the flocs. The interspecies electron transfer reaction was mildly diffusion controlled. The H 2 gas profiles across the flocs showed high H 2 concentrations inside the flocs at any time. Simulations of the syntrophic metabolism at low substrate concentrations such as in digestors or sediments showed that it is impossible to achieve high H 2 gas turnovers at simultaneously low steady-state H 2 concentrations. This showed a mechanistic contradiction in the concept of postulated low H 2 microenvironments for the anaerobic digestion process. The results of the computer experiments support the conclusion that syntrophic H 2 production may only be a side reaction of H 2 independent interspecies electron transfer in methanogenic ecosystems. | en_US |
