Abstract: The diffusion controlled growth morphology and kinetics of E.coli colonies under different experimental conditions, have been studied. Fractal dimension is calculated by box counting method and found to be 1.55 ± 0.03. A transition from Eden-like to smooth spreading colony patterns was observed. Influence of vitamins, H2O2, antibiotics and Bacillus subtillis on growth behaviour has been studied. Burst morphologies in E.coli and phthalic acid are observed similar to diffused growth in hepatocellular carcinoma and black sea fan. Vitamin C and vitamin B complex showed stimulatory effect to some extent while oxytetracyclin and H2O2 inhibited the growth of the microorganism. E coli and Bacillus subtilis, grow independently when cocultivated on the same plate.
