Unformatted text preview: are multiple ways of getting the same amount of dilution. The results of the dilution plate showed, very distinctly, the differences in the F, G, and H samples. The plates for the stock, B, and D tubes looked very similar to each other with no distinct colonies. Although there were too many colonies to count (over 300), on the plates for sample F, you could make out distinct colonies. Plate G had an average of 38 colonies per plate so that was the one used to calculate the original titer and plate H did not have enough average colonies (<10). At an O.D. of 0.6 the titer would be 3.59 x 10 7 CFU/ml....
