Fig. (6) Dependence of mutant motility phenotypes on IPTG. Motility mutants
KV7432 and KV7433 were grown at 28°C in TB-SW motility medium containing the
indicated concentrations of IPTG. The average diameter of migration of
triplicate samples after 5 hours is shown. Standard deviation is indicated by
error bars. Error bars smaller than the plotted points are occluded by the
points and not visible.
