Effect of gentian violet and ferric ammonium citrate on PA planktonic cultures. OPPA8 and PAO1 planktonic cultures were initiated in LB at 37°C and 250 rpm. GV at 1225, 122, and 12.2 μmol/L and FAC at 100 and 250 μmol/L were added to cultures. OD600 was then measured at 1, 2, 3, 4, 6, 9, 15, and 24 hours after dilution and compared with control planktonic growth in LB only. GV at 1225 μmol/L delayed the onset of logarithmic expansion and slowed the rate of expansion of OPPA8 and PAO1 planktonic cultures. GV at 122 μmol/L slowed the rate of growth for both OPPA8 and PAO1, but only delayed the onset of logarithmic growth in PAO1. GV at 12.2 μmol/L had no effect on OPPA8 or PAO1 planktonic growth. FAC at 100 and 250 μmol/L had no effect on planktonic growth of either OPPA8 or PAO1.
