Plate count agar (PCA) is a microbiological growth medium commonly used to assess or to monitor "total" or viable bacterial growth of a sample. PCA is not a selective medium.
The composition of plate count agar may vary, but typically it contains (w/v):
-
- 0.5% peptone
- 0.25% yeast extract
- 0.1% glucose
- 1.5% agar
- pH adjusted to neutral at 25 C.
Plate count broth does not contain agar.
Famous quotes containing the words plate and/or count:
“Then he rang the bell and ordered a ham sandwich. When the maid placed the plate on the table, he deliberately looked away but as soon as the door had shut, he grabbed the sandwich with both hands, immediately soiled his fingers and chin with the hanging margin of fat and, grunting greedily, began to much.”
—Vladimir Nabokov (1899–1977)
“Every country has its own constitution; ours is absolutism moderated by assassination.”
