Expert Solution
Step 1
It is very difficult to determine the concentration of the bacteria in a solution. So, the process of serial dilution method is used to determine the bacterial concentration of a solution. In this method various dilution of the original sample is prepared and plated. Only the countable plate is considered for the determination of the bacterial concentration. Plate having 30 to 300 cfu count is considered for the calculation of bacterial concentration.
