Standard curves relating log of CFU with respect to the norm of the Log of slope of MB reduction. (a) Total metabolic active cell count versus MBRT slope. Symbol open triangle represents experimental points. In this case, Log (MBRT slope) and Log (CFU) were fitted as a straight line. Solid line represents best fit with R2 = 0.99. Best-fit equation is given by Y = −4.7* X + 24. (b) Total metabolic active E. coli count versus MBRT slope for the mixed culture. Symbol open triangle represents experimental points. In this case, Log (CFU) and Log (MBRT slope) were fitted as a straight line. Solid line represents best fit with R2 = 0.99. Best-fit equation is given by Y = −4.8* X + 21.5. (c) Total metabolic active B. subtilis count versus MBRT slope for the mixed culture. Symbol open triangle represents experimental points. In this case, Log (CFU) and Log (MBRT slope) were fitted as a straight line. Solid line represents best fit with R2 = 0.98. Best-fit equation is given by Y = −4.2* X + 19.882.
