FIG 2.

Evolution of resorufin (RF) fluorescence overtime with the capsulated strain ATCC 49619 (gray squares) and the noncapsulated strain R6 (black circles) in planktonic cultures (left panel) using starting inocula at an OD₆₂₀ of 0.1 (open symbols) or 1 (closed symbols) or in biofilms (middle and right panels) at different maturity stages (2- and 11-day-old naive [open symbols] and induced [closed symbols] models). All values are means ± standard deviations (SD) of 3 independent determinations. When not visible, the SD bars are smaller than the size of the symbols.
