Be aware if any progress is observed on aerobic plate and Examine to advancement on anaerobic plates.  Continue with identification when isolation is complete. 

If inadequate information regarding the merchandise exists to evaluate its probable advancement inhibiting action.

Notice if any growth is observed around the anaerobic plate which differs from advancement within the aerobic plate. Choose only one representative colony and accomplish an aero-tolerance test to be able to determine if a rigid anaerobe has been recovered. Carry on with identification of any stringent anaerobes recovered when isolation is entire.  

The technician need to be educated in the strategy of detecting growth in the incubation period of time. Progress is decided by viewing the media, which is usually distinct and clear, towards a lightweight source. Turbid (cloudy) spots during the media are indicative of microbial progress.
