Study Notes

Aseptic Technique and CFU/mL Determination

Aseptic technique is crucial for preventing contamination in microbiological practices.
Ensures the growth of specific microorganisms without interference from others.

Colony-Forming Units (CFU)

CFU refers to a visible mass of microorganisms derived from a single microbial cell.
Essential for quantifying microbial populations in a sample.

Expression of Results

Microbiological enumeration results are typically reported as CFU/g or CFU/mL.
CFU/g indicates the number of colony-forming units per gram of a sample.
CFU/mL signifies the number of colony-forming units per milliliter of a liquid sample.
