Fluorescence microscopic 3D reconstitutions and quantification of biofilms formed on glass surfaces under static conditions. After 24 h of growth under static conditions, biofilms were stained with DAPI. Microscopic 3D images were reconstituted (a), the average thicknesses of the biofilms were determined and the differences between them were statistically tested (b). A, B, C, D, E: bacterial isolates from mudflat biofilms. F, G: bacterial isolates from corrosion product-microorganism composite biofilms. Scale bar: 200 μm. CP: percentage of colonized surface. These values are averages of data from three independent experiments, with standard deviations lower than 10 % of each value. *: p < 0.05; **: p < 0.01; ***: p < 0.001. ns: not significant. Circles with the same color indicate bacteria with no significant biofilm thickness differences. Blue circles: thickest biofilms. Red circles: thinnest biofilms. Black circle: intermediate thickness
