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:
“Say “Yessum” to the ladies, an’ “Yessur” to the men,
And when they’s company, don’t pass yer plate for pie again;
But, thinkin’ of the things yer’d like to see upon that tree,
Jes ‘fore Christmas be as good as yer kin be!”
—Eugene Field (1850–1895)
“I count myself in nothing else so happy
As in a soul remembering my good friends.”
—William Shakespeare (1564–1616)
