  • Publication number: 20190017093
    Abstract: A process for determining the viability of a biological indicator includes exposing the biological indicator to a viability detection medium, the biological indicator including test microorganisms, the exposing the biological indicator to the viability detection medium producing a gaseous reaction product when one or more of the test microorganisms are viable. The presence or absence of the gaseous reaction product produced by the biological indicator combined with the viability detection medium is detected with a sensing device, the sensing device comprising a capacitive sensor, wherein the presence of the gaseous reaction product indicates the presence of viable test microorganisms and the absence of the gaseous reaction product indicates the absence of viable test microorganisms. A sterilization detection device includes a container configured to contain the biological indicator, a viability detection medium, and the sensing device.

  • Publication number: 20150373986
    Abstract: This invention relates to an aqueous composition and a process for killing spores. The process may comprise contacting the spores with the aqueous composition for a sufficient period of time to effect a desired reduction (e.g., at least a 4 log reduction) in the number of spores capable of returning to vegetative growth. The aqueous composition may comprise water, an antimicrobial agent (e.g., peracetic acid) and a peroxide (e.g., hydrogen peroxide). The process may be a two-step process involving the use of a first aqueous composition, which may comprise water and the peroxide, and a second aqueous composition which may comprise water and the antimicrobial agent.
