Steam Sterilization | Disinfection & Sterilization ...

The oldest and most recognized agent for inactivation of microorganisms is heat. D-values (time to reduce the surviving population by 90% or 1 log 10) allow a direct comparison of the heat resistance of microorganisms.Because a D- can be determined at various temperatures a subscript is used to designate the exposure temperature (i.e. D 121C).
