The relationship between the number of colony-forming units (CFUs) per well and counts
per second (cps) of bioluminescence intensity. CFUs were measured by plating for single
colonies at various time points during exponential growth (black) and at the end of
exponential growth (gray). The linear fit corresponds to 30 CFUs per well per cps.
This linear relationship holds throughout four orders of magnitude of exponential
growth; it breaks only at high cell densities, when the population enters stationary
phase.
