Formatted Abstract/Summary
Interspecies electron transfer (IET) plays an important role in facilitating the thermodynamically limited acetogenesis and methanogenesis in anaerobic digestion. An individual based Lagrangian model accounting for different microbial morphologies as well as variable geometry resulting from forces acting on the cells and cell links has been developed to describe indirect IET (electron transport through shuttle compounds) and a more recently proposed mechanism, direct IET through conductive pili (nanowires). Preliminary one-dimensional and three-dimensional results at cellular scale for indirect IET show a pH drop at the acetogen and slight increase at the methanogen, while the direct IET model predicts a slight pH drop at the acetogen and a stronger increase at the methanogen. In this presentation, modelling results on the feasibility of direct IET versus indirect IET in microbial communities will be shown and discussed.
