-gfp∷minD] (c) were
grown in Medium B in the presence of 10 μM IPTG and 0.0005%
arabinose for 5 h. Generation times were 72, 62, and 61 min, and
cells were harvested at OD600 0.86, 1.06, and 1.0 for
panels a, b, and c,
respectively. Unfixed cells were examined by using identical exposure
times (0.4 s) for capture of the fluorescent images.
