Modeling metabolic networks of individual bacterial agents in heterogeneous and dynamic soil habitats (IndiMeSH)

Strategic analysis of pore size distribution and hydration conditions.
Visualization of the degree of connectivity for all three pore networks with varying mean pore size at two hydration conditions. (a) Histogram of pore sizes taken from lognormal distributions with varying mean and standard deviations. (b) Resulting soil water characteristic curve including indications of matric potential taken as wet (-1 kPa) and dry (-10 kPa) conditions. (c) Calculated relative diffusion for all pore networks using the Milling-Quirk equation. (d) Bacterial growth dynamics depending on pore network and hydration condition for the whole simulation time of 120 h. (e) Bacterial consumption for the small pore size network and varying hydration conditions. (f) Spatial distribution of acetate production and consumption. Acetate is produced at the carbon rich center due to overflow metabolism (electron acceptor limited) and consumed at the periphery via aerobic respiration.
