Characterization of the E. coli Lux bacteria culture. Optical density measurement (OD_600nm), the measured and calculated CFU/mL values, the mean of bioluminescence signals measured in 5 μL of a 1 : 2 E. coli Lux dilution, and correlation coefficient between colony forming units and photon per second values as are shown.

Test round	OD600 nm	CFU/mL	Mean (p/s)	(CFU/mL vs. p/s)
Pretest 1	3.011		7.76+10	0.956
Pretest 2	3.065		1.29+09	0.8919
Main study	3		1.46+10	0.9510
