Unformatted text preview: . For test tubes 5 and 6, the results are negative; g = g = 0 = . Therefore, g GG = g g g g g g g . We graph g GG vs. concentrations and get the following chart. From the chart, we can tell that MPN is 0.2 cells / mL, which is 20 cells / 100mL. Comparing this to the undisinfected water bacterial concentration 10 cells / L, which is 10 cells / 100mL, the disinfection efficiency is N/N0 = 0.0002 = 2 10 , which is 4-log removal. 0.0002 0.0004 0.0006 0.0008 0.001 0.0012 0.0014 0.1 0.15 0.2 0.25 0.3 P_total Concentrations (cells/mL) P_total vs. Concentrations P_total vs. Concentrations...
