^a95CIL, lower limit of the 95% confidence interval.

^b95CIU, upper limit of the 95% confidence interval.

^cPredicted means of ln(CFU + 0.01)-transformed values from SLR equations for three conditions (the wild-type and two mutant strains) within a day followed by the same letter are not significantly different based on overlap of their respective 95% confidence intervals.
