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
Radius temperature and brightness
