What are the five sterilization processes mentioned in the text?
Steam (moist) Sterilization, Dry Heat Sterilization, Filtration Sterilization, Gas Sterilization, Ionization Sterilization
What factors should be considered when selecting the appropriate sterilization method?
The nature and amount of product, and whether the product and container-closure system will have a predominately moist or dry environment during sterilization
Name three general categories in which microorganisms can be categorized for sterilization purposes.
1- Easy to kill with either dry or moist heat, 2- Susceptible to moist heat but resistant to dry heat (Bacillus subtilis), 3- Resistant to moist heat but susceptible to dry heat (Colstridium sporogenes)
What are sterilization tests performed to verify?
That an adequate sterilization process has been carried out
For what purposes are gas and ionizing radiation sterilization commonly used?
Devices and surgical materials
What are the three parts of an autoclave?
Pressure chamber, Lid, Electrical heater
How does an autoclave kill microorganisms?
Moist heat kills microorganisms via coagulation of proteins
Why is an autoclave such an effective sterilizer?

What are the two categories of methods for inactivating microorganisms?
Physical and chemical
What is the main principle of autoclave operation?
Steam penetrates objects in the autoclave, condensation creates negative pressure and draws in additional steam, moist heat kills microorganisms via coagulation of proteins
