Calculate the total number of bacteria in your yogurt container three times (in duplicate). Begin by choosing a dilution plate that has 30-300 colonies on its surface. This will be your #CFU's/#ml #CFU's x Dil Factor x Tube 1 total vol (ml) x yogurt container mass (g) = total # of bacteria in yogurt (g) in Tube 1 yogurt container #ml 1 4. Since you have two plates with the same dilution (duplicates), calculate the total number of bacteria in your yogurt two times. Circle your three answers. Make sure to include the correct values with your numbers. 5. Average your two answers above for a more accurate representation of the total number of bacteria in your yogurt container.
