Anaerocult™ A is a reagent mixture used in microbiology to create an anaerobic environment to enable the growth of facultative and obligatory anaerobic microorganisms. Anaerocult™ A contains chemical components that bind the free oxygen in the atmosphere, producing carbon dioxide and establishing an anaerobic environment. The reaction is initiated by slightly moistening the reagent mixture, and incubation should be carried out in an Anaerobic jar or bag. For best results, Anaerocult™ A is used along with Anaerocult™ strips.
