However, when calculating MPN combinations, I found out that this number was too small to accommodate each and every possible combination, including the ridiculously unlikely ones.

• The MPN method has direct application in quali­ fication studies for media and for alternate (rapid) microbiological methods. It has also been suggested as a consideration for an alternate method to trend environmental monitoring studies.

To transfer results to Excel: select all text on the Print Preview, copy the text, and paste the text from the clipboard into Excel. Calculate an Additional MWQP. The values are at the 95% confidence limit for each of the MPN determined. These values are prepared for 10,1 and 0.1mL combination. If the combination is 100, 10, 1mL, the MPN is 0.1 times the value in the table. If on the other hand a combination corresponding to 1, 0.1, and 0.01 mL is planted, record MPN as 10 times the value shown in the table.I wrote an R script for calculating MPN. The Most Probable Number (MPN) method is a long-standing way of calculating the concentration of bacteria in a sample (usually expressed as cells/100 mL).
