General description

Oxyrase for Broth is a sterile enzyme formulation that uses the Oxyrase Enzyme System to produce anaerobic conditions in different bacteriological broth media. Oxyrase for Broth facilitates growth of anaerobes, such as for reviving lyophiles. Oxyrase for Broth is a ready-to-use product that renders broth anaerobic in 10-15 minutes, and continues to remove oxygen from the container headspace beyond that time.


Oxyrase® for broth has been used in reinforced clostridial media to provide an anaerobic environment for culturing Bifidobacterium adolescentis. It has also been used as a component in PMM/imaging media for oxygen-free microscopy experiments to remove oxygen.

Biochem/physiol Actions

Oxyrase® for broth is useful to cultivate species like Shigella sonnei and Shewanella oneidensis.It also provides anaerobic conditions for cultivating species like Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa.

Storage and Stability

Store at -20 °C. (Long Term Storage)

Analysis Note

Obesity and obesity-related metabolic disorders are linked to the intestinal microbiome. However, the causality of changes in the microbiome-host interaction affecting energy metabolism remains controversial. Here, we show the microbiome-derived metabolite δ-valerobetaine (VB) is a diet-dependent obesogen that is increased
