m e usually performed, e.g., 10°>10% 10% 10%, etc. Two-fold or other dilution schemes can be applied as well. For accurate quantitation, it is important to use the selected dilution scheme consistently. correction factor is 10 (0.1 ml X 10-10 ml). If you plated 0.5 ml, the correction factor is 2. 1.-CFU/Dr Initial concentration, (lc) equals colony forming units (cfu) divided by dilution factor (Df). Note that each step of the dilution procedure reduces the...

Draw (or describe) a dilution scheme for making the following bacteriophage titer plates: 1:100 (10-2), 1:1000 (10-3), and 1:10,000 (10-4) using a maximum of 2 dilution blanks. Show (or include in your description) all of the volumes including transfers, amounts in tubes and amounts plated.

Name One use of serial dilutions is to calculate the concentration of microorganisms. Since it would usually be challenging or even impossible to actually count the number of microorganisms in a sample, the sample is diluted and plated to get a reasonable number of colonies to count (usually between 25 to 250 colonies is the goal). Since each colony on an agar plate theoretically grew from a single microorganism,...

Problem solving Question: 1. If you were to serially dilute a sample with three 1:10 dilutions, what would be the final dilution of the last tube? 2. If you add 1 ml of sample to 99 ml of water, and then add 0.1ml (100pl) to the agar plate what is the dilution of the sample on the plate? 3. If you count 98 colonies on the 10-5 plate, how many bacteria/ml were in your sample? 4. What are three ways...
