Fig 3. Growth rate analysis of WT, mut-1, and mut-2 in response to increasing concentrations of benzalkonium chloride.

Each culture was grown at room temperature for 48 hr and the growth rate was measured using the oCelloScope. (A) Growth curve of WT and mutant strains based on the total absorption (505nm wavelength) values in each microtiter well. (B) Growth curve of WT and mutant strains based on background corrected absorption (BCA) values. Growth rate was measured in 3 biological replicates for each sample. WT, mut-1, and mut-2 are depicted by red, light blue and purple lines, respectively.
