What is the concentration of a suspension that grew 89 colonies on a plate with a dilution of 1:100?
mafiozo [28]

Answer:

8900 CFU/mL

Explanation:

Colony Forming Units (CFU) is a value that indicates the degree of microbiological contamination of an environment. It expresses the relative number of microorganisms of a given taxon in a volume of one cubic meter of water.

UFC is the minimum number of separable cells on the surface, or inside, of a semi-solid agar medium that results in the development of a visible colony of the order of tens of millions of descending cells. The CFUs can be pairs, chains or clusters, as well as individual cells. Colony forming unit.

Calculation

Colonies * Dilution = CFU/mL

89          *  (100/ 1 mL) = CFU/mL

8900 CFU/mL
