Environmental and ecological controls of the spatial distribution of microbial populations in aggregates
Fig 9
Individual-based Model description.
(A) Representation of simulation domain. An expansion of specific aggregate zone (bottom-right square), and an example of the initial distribution of cells (top-right square) are shown, where microbes are represented as coloured circles with a specific radius: B1 –purple circle; B2 –green circle; B3 –orange circle. (B) Hypothetical position of microbes in the node. Only “microbe A” belongs to node i,j because its centre is inside the node. (C) Microbial division and inactivation. α is any stochastic value between 0.45–0.55. Mmax and Mmin refer to the maximum and minimum mass that microbe can reach, respectively.
