描述: Anaerocult® system is a reliable and established system for the cultivation of obligate and facultative anaerobes. The Anaerocult® system is based on sachets made of highly absorptive and highly gas permeable paper. The sachets, of different sizes, are filled with an oxygen-binding reagent mixture which also produces carbon dioxide. Water is added to start the reaction, which consists of the oxidation of finely divided iron and release of CO₂. The reaction proceeds without a catalyst. Incubation is possible in an anaerobic jar or in bags.
