A bacterial culture was grown for 12 hours. At 4-hour interval, the culture was sampled to determine the population of the culture, by transferring 25 mlof the suspension to 225 ml 0.90% Nacl. Three consecutive dilutions were further made by using 1 mlaliquot in 9 mlof 0.90% Nacl. One ml from each dilution was plated in each of duplicate plates. The following table shows the results of the plating method.
