Abstract: A method of disinfecting a medical device comprises three steps. First, a disinfectant is contacted with a process indicator and the medical device. The disinfectant comprises at least one aldehyde. The process indicator contains a synthetic amine-containing compound disposed on a substrate. The synthetic amine-containing compound comprises at least one of primary amino groups or secondary amino groups, and is reactive with the disinfectant to form at least one adduct. The synthetic amine-containing compound and the medical device are in fluid communication through the disinfectant. A predetermined disinfectant exposure criterion exists for contacting the disinfectant with the medical device. Second, the process indicator is spectrally observed and at least one parameter is obtained therefrom that is predictive of the predetermined disinfectant exposure criterion. The third step is determining that the predetermined disinfectant exposure criterion has been achieved.

Abstract: A culture system for culturing a microaerophilic or an anaerobic microorganism is provided. The culture system can include effective amounts of i) an enzyme of an oxidoreductase family and ii) a substrate for said enzyme, a container, and a predetermined volume of aqueous medium that supports growth of said anaerobic or microaerophilic microorganism. The enzyme can be selected from a group consisting of ascorbic acid oxidase and laccase. The effective amounts are effective to deplete dissolved oxygen in the predetermined volume to a concentration that facilitates growth of a microaerophilic microorganism or an obligately-anaerobic microorganism. A method of using the system is also provided.

Abstract: A method of making a flowable, dried agglomerated nutrient medium is provided. The method comprises introducing a nutrient component comprising a powdered nutrient, and an agglomeration liquid, into an agglomerator comprising a flow-through-type agglomeration chamber, wet-massing the nutrient component with the agglomeration liquid in the agglomeration chamber for a predetermined period of time to form agglomerated nutrient medium particles, and exposing the agglomerated nutrient medium particles to drying conditions for a period of time to form the dried, agglomerated nutrient medium. The nutrient component facilitates the growth of a microorganism. Compositions, articles, and kits comprising the flowable, dried agglomerated nutrient medium are also provided.
