FIG. 5.

MCD on the surface of biofilm and suspension culture of S. aureus Phillips cells. Secondary suspension culture cells (horizontally striped bars) were harvested at characteristic growth phases: early growth (∼3 h), mid-growth (∼9 h), late growth (∼17 h), and stationary (∼22 h). Planktonic cells (gray bars) were collected at 4-h time intervals, and sessile cells (diagonally striped bar) were collected after 24 h of biofilm growth. Asterisks represent statistical significance (P < 0.05) with respect to primary culture cells (checkered bar). Reported values are means ± standard deviations of duplicate experiments.
