    Abstract: An article for assessing efficacy of a sterilization process is provided. The article includes a housing, a plurality of genetically-modified spore-forming test microorganisms disposed in the housing, a liquid medium disposed in an openable container that is disposed in or attached to the housing, and an enzyme substrate disposed in the housing or in the openable container. The genetically-modified test microorganism comprises a functional fusion gene that encodes a non-naturally occurring chimeric protein, the chimeric protein comprising a first segment and a second segment that is contiguous with the first segment. The first segment comprises at least a portion of a first polypeptide that is normally found in spores and the second segment comprises a second polypeptide having a detectable enzymatic activity. The enzyme substrate is capable of reacting with the detectable enzyme activity to form a detectable product. A method of using the test microorganisms is also provided.

  • Patent number: 11333571
    Abstract: The invention provides a dynamic seal test device for cryogenic fluid medium. The dynamic seal test device includes stator unit, rotor unit, slipway, servo motor unit and sensors. The tested seal is installed inside the stator, and the thermal insulation stator and vacuum rotor together form a dynamic seal test structure. The seals and shaft sleeves can be flexibly replaced, which is beneficial to study the influence of different seal types, structure, and seal land configurations on the sealing performance. The servo motor provides power for the rotor and controls the rotation speed. The device greatly improves the thermal insulation capacity to avoid the gasification for the cryogenic fluid medium induced by the heat transfer from environment so that ensuring the stability of the test device.
