Values are average of six optical fibers from three independent experiments with bacterial concentration of 5 × 108 cfu/mL and background (control) signal values, i.e., fibers exposed to buffer only are presented in separate column. Positives values were assigned based on Tukey’s grouping at P < 0.05.
