FIG. 2.
Hg uptake. PHL628 and PHL628 csgA cultures harboring pmerRGFP grown for 24 h in GMM at 30°C were harvested and exposed to total Hg concentrations ranging from 0 to 3 μM. The green fluorescence and OD600 values of the cultures were recorded for the following 4 h. For each condition, the fluorescence was divided by the OD600, and the resulting values from three independent experiments were averaged and plotted versus time. Error bars represent standard deviations of the results for triplicate samples. Results at 4 h after Hg introduction are shown.
