      A tenfold serial dilution (dilution factor of 10). Note that at each step, the previously diluted solution provides 10% of the solution in the next step. Other dilution factors can be used, as well. This procedure can be used to produce an extremely dilute reagent, depending on how many dilution …

      Justification: If the 1.0 mL plate is deemed TNTC, then the actual count is likely to be somewhere between 20,000 (maximum count for a 1.0 mL dilution) and 200,000 (maximum count for a 0.1 mL dilution). The TNTC number of 63,200 is the geometric mean of those two numbers. Page 1 of 2. For the Colilert Using Quanti-tray Procedure:

      So then, if we have a D-value of 4.5 minutes at 150℉, we can calculate D-values for 160℉ by reducing the time by 1 log. So, our new D-value for 160℉ is 0.45 minutes. This means that each 10℉ increase in temperature will reduce our D-value by 1 log. Conversely, a 10℉ decrease in temperature will increase our D-value by 1 log.
