Figure 7.

dSTORM images of the capsular brush rafts after temperature upshifting from 20 to 37 °C. The nucleation and expansion of the capsular brush rafts are shown in the sequential images (a) and (b). (c) shows the rafts from three sequential times superposed. Red is the initial time point (20 °C), yellow 10 min after temperature upshifting (37 °C), and magenta 20 min after temperature upshifting (37 °C). The scale bars are all 1 μm. (d) Radius of gyration (R_g) of the lyso-PG rafts as a function of time after upshifting the temperature. The expansion process is well described with a logistic function (red line). The error bars are from repeat experiments and are due to variations of capsule emergence on the bacterial cells.
