FIG. 11.

Flat versus irregular topology. Flow cell biofilms of green fluorescent protein-tagged P. aeruginosa grown with different carbon sources are shown. These images were acquired 48 h after inoculation of the system. Biofilms grown with succinate have a flat topology characterized by high surface coverage and low height; those grown with glucose have an irregular topology characterized by low surface coverage and dispersed pillars of bacteria. SV, side view (xz plane); TD, top-down view (xy plane). Gridlines are spaced 20.1 μm apart. (Reprinted from reference 289 with permission of Blackwell Publishing Ltd.)
