Detailed explanation-1: -The suitable colony counting range (10) is 25-250. The automated spiral plate count method for the examination of foods and cosmetics (5), outlined below, conforms to AOAC Official Methods of Analysis, sec. 977.27.
Detailed explanation-2: -If there are less than 30 colonies on the plate, small errors in dilution technique or the presence of a few contaminants will have a drastic effect on the final count this count is called too few to count (TFTC).
Detailed explanation-3: -Counts of such organisms, grown as colonies on or in nutrient agar, provide a useful means of assessing the general bacterial content of a water. The colony count, or plate count, following incubation at 20–22°C gives an indication of the diversity of bacteria present at normal environmental temperatures.
