FIG. 5.

Evolution of cell length during the growth of cells on a gold surface at a potential of −0.2 V (closed symbols) or 0.5 V (open symbols). Different symbols correspond to cells originated at increasing experimentation times (•, 42 min; ▪, 72 min; ▴, 96 min; ○, 57 min; □, 81min; and ▵, 93min). Lines indicate the exponential growth fitting results used to calculate the elongation rates of individual bacteria (see Materials and Methods). Inset, elongation rates calculated by differentiation of the exponential growth fitting results.
