Total Viable Count

Total Viable Count (TVC) gives a quantitative idea about the presence of microorganisms such as bacteria, yeast and mold in a sample. To be specific, the count actually represents the number of colony forming units (cfu) per g ( or per ml) of the sample.

A TVC is achieved by plating dilutions of the culture until 30-300 colonies exist on a single plate.

Famous quotes containing the words total and/or count:

    Computers are good at swift, accurate computation and at storing great masses of information. The brain, on the other hand, is not as efficient a number cruncher and its memory is often highly fallible; a basic inexactness is built into its design. The brain’s strong point is its flexibility. It is unsurpassed at making shrewd guesses and at grasping the total meaning of information presented to it.
    Jeremy Campbell (b. 1931)

    We do not mean to count or weigh our contributions by any standard other than that of our abilities.
    Thomas Jefferson (1743–1826)
