  1. Column 1: activation of QS = bold. Growth control = 0, 3.7*10-8M HHL = 1. Column 2: growth stimulation (> 1.15) = bold, growth inhibition (< 0.6) = italics, growth control = 1. Column 3: inhibition of QS induced by 3.7*10-8M HHL (< 0.60) = italics, control = 1. Column 4: inhibition of QS induced by 10-6 M HHL, > 0.15 less inhibitory than column 3 = bold, > 0.15 more inhibitory than column 3 = italics, control = 1. Column 5: synergistic effect to HHL = bold, control = 1.
