Final answer:
Anaerobic organisms are cultured using an anaerobic jar or chamber, which allows growth in an oxygen-free environment utilizing chemical packs or an oxygen-excluded box with glove access.
Step-by-step explanation:
The system used to culture anaerobic organisms as discussed in Exercise 2-7 is an anaerobic jar or an anaerobic chamber. These systems are designed to grow obligate anaerobic bacteria, which require environments devoid of oxygen. An anaerobic jar typically includes chemical packs to remove oxygen and release carbon dioxide, creating a suitable environment for anaerobic growth.
The anaerobic chamber is an enclosed box that has oxygen removed from it and features gloves that allow for manipulation of the cultures without exposing them to air. This ensures that obligate anaerobes can be cultured effectively without coming into contact with oxygen, which is lethal to them.
