Fig. 8: Colonization of a randomly corrugated surface by E. coli.
From: The effect of flow on swimming bacteria controls the initial colonization of curved surfaces
a Fluorescent image acquired at channel mid-plane of GFP-tagged E. coli wt cells attached to the lateral corrugated surface of a microfluidic channel (height = 100 µm) after 3 h of flow of a diluted bacterial suspension at a mean flow velocity of U = 150 µm s−1. b Intensity distribution of the fluorescent signal shown in a, normalized by its maximum value. c Normalized attachment density of cells (elongation q = 8.5, swimming speed V = 21.6 μm s−1) on the corrugated surface obtained with the model at a mean flow velocity of U = 150 µm s−1 (U/V = 6.9).
