CFU/mL: What it is and how it's used

CFU/mL stands for 'colony forming units per milliliter.' It is a unit used to measure the concentration of viable microorganisms in a liquid sample. The CFU/mL count represents the number of individual colonies that are capable of growing and forming visible colonies on a solid growth medium. It is commonly used in microbiology and microbial testing to determine the level of contamination or the effectiveness of antimicrobial treatments.
