Environmental and ecological controls of the spatial distribution of microbial populations in aggregates
Fig 8
Influence of shear force (detachment) to spatial distribution of microbial populations.
A maximum radius of 30 Ī¼m was set when detachment was considered. Aggregates captured at 50 d. Three conditions were evaluatedācompetition ([S]T = 0.2 mM), commensalism ([S]T = 0.1 mM), and commensalism + competition ([S]T = 0.1 mM and [O2] = 10 mg/L). Inactive bacteria are shown in a lighter colour. Substrate profiles on the transverse plane of aggregates have been included on S11 Fig. The simulation experiments including detachment were started with the same inoculum as those without detachment with the objective to observe the genuine impact of the shear force in the spatial distribution of the microbial populations.
