MIC of pyochelin in the presence of selected additives.

MIC values are expressed in µM.ND = Not Determined.R = Resistant (no inhibition observed) to pyochelin at a concentration of 3 mM.aM9 medium.bM9 medium supplemented with 1 mM ascorbic acid.cM9 medium supplemented with 100 µM FeCl3.dM9 medium supplemented with 1 µM enterobactin.eM9 medium supplemented with 50 µM citrate.MIC（最低抑菌浓度，Minimum Inhibitory Concentration）值以微摩尔（µM）为单位。ND=未测定（Not Determined）。R表示对3 mM浓度的脓杆菌素（pyochelin）耐药（未观察到抑制作用）。 a. M9培养基（M9 medium）。 b. 添加1 mM抗坏血酸（ascorbic acid）的M9培养基。 c. 添加100 µM氯化铁（FeCl3）的M9培养基。 d. 添加1 µM肠杆菌素（enterobactin）的M9培养基。 e. 添加50 µM柠檬酸盐的M9培养基。
