Whenmedia is in a tube the diffusion of O2 back into the broth or agar |
|
|
Agar Deep Stab |

|
Most common reason why anaerobicconditions were NOT achieved (i.e., methylene blue indicator strip remainsblue) |
•incomplete gasket seal (if an anaerobic jaris used) •a hole (if a plastic pouch/bag is used) |
