Figure 4From: Multidrug resistance protein MdtM adds to the repertoire of antiporters involved in alkaline pH homeostasis in Escherichia coli Choline, chloride or sucrose do not support growth of E. coli cells complemented with mdtM at alkaline pH. Growth of E. coli BW25113 ΔmdtM cells complemented with wild-type mdtM in salt-free liquid medium buffered to pH 9.5 in the presence of 0 mM, 20 mM, 40 mM or 86 mM choline chloride (A), sucrose (B), sodium gluconate (C) and potassium gluconate (D). Data points and error bars represent the mean ± SE of three independent experiments.Back to article page
