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:
“Of lower states, of acts of routine and sense, we can tell somewhat; but the masterpieces of God, the total growths and universal movements of the soul, he hideth; they are incalculable. I can know that truth is divine and helpful; but how it shall help me I can have no guess, for so to be is the sole inlet of so to know.”
—Ralph Waldo Emerson (1803–1882)
“But for us the road
unfurls itself, we count the
words in our pockets, we wonder
how it will be without them, we don’t
stop walking, we know
there is far to go....”
—Denise Levertov (b. 1923)
