Figure 1From: Effect of overexpressing nhaA and nhaR on sodium tolerance and lactate production in Escherichia coliMaximum specific growth rate (μ MAX ) of MG1655/pTrc99A- nhaA (○, ●) and MG1655/pTrc99A- nhaR (◊, ♦) at low (<0.10 M) Na+concentration (hollow symbols) and at 0.75 M Na+concentration (solid symbols). The specific growth rate of MG1655 was about 0.69 h-1 with <0.10 M Na+ and 0.17 h-1 at 0.75 M Na+ concentration.Back to article page
