Plot of bacterial concentration vs. their absorbance ratio. (a) Plot of E. coli O157:H7 concentration vs. absorbance ratio (A620/A520) for the E. coli O157:H7 assay. (b) Plot of S. typhimurium concentration vs. absorbance ratio (A620/A520) for the S. typhimurium assay. Error bars represent standard deviations from three independent assays.
