Environmental and ecological controls of the spatial distribution of microbial populations in aggregates

Eco-interaction modulus diagram for simulations considering commensalism and competition for O2 with [A] = 1.0–0.1 mM and [O2] = 14–1 mg/L.
Aggregates captured at steady state (75 d for [S]T = 1.0 mM and [O2] = 1 mg/L; 50 d for all other conditions). Inactive bacteria are shown in a lighter colour. Eco-interaction modulus calculated by Eq 1 for each replicate. Colour legend: B1 –purple; B2 –green; B3 –orange.
