Colony count microbial

Colony count, microbial
Enumeration by direct count of viable, isolated bacterial or fungal cells or spores capable of growth on solid culture media. Each colony (i.e., microbial colony-forming unit) represents the progeny of a single cell in the original inoculum. The method is used routinely by environmental microbiologists for quantifying organisms in air, food, and water; by clinicians for measuring patients microbial load; and in antimicrobial drug testing.
