Abstract
A rapid method of determining the efficacy of a sterilization cycle, and an indicator adapted to perform such method, comprising subjecting to the sterilization cycle a source of active enzyme having activity which correlates with the viability of a microorganism commonly used to monitor sterilization, and incubating the enzyme source, following the completion of the sterilization cycle, with an effective amount of a substrate system capable of reacting with any residual active enzyme to produce a detectable enzyme-modified product.
