Fig. 1. Bacteria of different concentrations at 16hr of
incubation
A. R. solanacearum F1C1 at high (~
105 CFU ml-1) concentrations have
slender, finger-like projected microcolonies. B. Microcolonies
of R. solanacearum appear more circular at low (~
104 CFU ml-1) concentrations.C-D. Microcolonies of E. coli devoid of twitching
motility exhibited similar shape at both high and low concentrations.
