The rolled tube method is commonly used for isolating anaerobic microorganisms. This method involves pouring melted agar into a test tube, allowing it to solidify, and then inoculating the agar with the sample. The tube is then rolled to distribute the sample and promote anaerobic conditions within the agar. Anaerobic organisms require low or no oxygen to grow, and the rolled tube method provides a suitable environment for their isolation.
