The formula to calculate the CFU/mL is:
\[ \text{CFU/mL} = N \times D \]
Where:
CFU/mL stands for colony-forming units per milliliter and is a measure of the number of viable bacteria or fungal cells in a sample. It is a common unit used in microbiology to estimate the concentration of microorganisms in a liquid culture. The CFU/mL value helps in understanding the level of contamination or the efficiency of bacterial growth under various conditions.
Let's assume the following values:
Using the formula to calculate the CFU/mL:
\[ \text{CFU/mL} = 150 \times 1000 = 150,000 \text{ CFU/mL} \]
The CFU/mL is 150,000 CFU/mL.
