WebThe full form of CFU can be Colony Forming Units. An understanding regarding colony forming units can be gained such as a measure of total count of bacterial cells that can be there in a lab sample or a probiotic supplement. The unit for this measure can be CFU/mL for liquids whereas CFU/gm for solids. This helps in indicating the total count ... WebOct 28, 2024 · If your spread plate is successful, after incubation, you will get isolated countable colonies evenly spread across the surface of the agar. Count the number of colonies and multiply it by the appropriate dilution factor to determine the colony-forming units (CFU) present per ml in the original sample.
