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

Softa [21]

Eccentricity of a body following an elliptical orbit defines how nearly circular the path of the object is. When the eccentricity of an orbiting body increases, it means that the body is moving in the most stretched out path.

aliina [53]

Answer:

Explanation:

Coexistence occur when individual occupying in a particular place are able survive with limited resources.

environmental variations that may occur and drift them apart.

Equalizing mechanism - they all try to be at the same pace to avoid been out compete, even though some are stronger they equalize their energy for all to manage the limited resources.
