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.
