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.
