What is the function of Bjorn bottle in microbiology?

The Bjorn bottle is a specialized container used in microbiology for the cultivation and preservation of anaerobic microorganisms. Its design allows for the creation of an oxygen-free environment, which is essential for the growth of anaerobes that cannot survive in the presence of oxygen. The bottle typically has a sealed lid and may contain reducing agents to maintain low oxygen levels. This enables researchers to study anaerobic bacteria and their metabolic processes effectively.
