What is the temperature range at which most microorganisms are killed using an autoclave?

• A. 100-120 F
• B. 120-130 F
• C. 130-150 F
• D. 150-170 F

Answer: (C)

The temperature range at which most microorganisms are killed using an autoclave is generally accepted to be between 130-150 degrees Fahrenheit. Autoclaves function by combining heat and pressure to effectively sterilize equipment, killing not only bacteria but also viruses and spores that are often resistant to standard disinfecting methods. When heat is applied, the moist heat denatures proteins and disrupts cellular processes, leading to the death of microorganisms. The specific range of 130-150 degrees Fahrenheit is critical because temperatures lower than this may not consistently achieve sterilization, while temperatures higher may be unnecessary for effective sterilization. Therefore, the proper understanding of temperature ranges is crucial for ensuring that sterilization processes are both safe and effective, as insufficient temperatures could lead to the survival of pathogenic organisms.
