Showing how the colony area growth rate changes over time as the bacteria area is exposed to various concentrations of the antibiotics.

Higher antibiotic concentrations lead to growth inhibition after varying time delays. A lighter hue corresponds with a lower antibiotic concentration. The lines show mean values with the shaded region indicating standard deviation between repeats. Each plot shows data from three or more repeats. The growth rates are binned to the nearest 30-minute interval. (PDF)
