Dilution of bacteria culture is carried out in comparison to McCfarlan standard so as to have a decent number of bacteria that will not be too numerous or too little to observe the growth of distinct colonies during culture preparation.
Without dilution, colonies may form but may be too numerous to count. Too much dilution may also lead to no growth in the culture plates.
