Solution Preview

You can test for the fermentation of mannitol is by using Phenol Red- Mannitol broth. This culture medium is just like Glucose, Lactose, and Sucrose tubes except that Mannitol is the fermentable organic compound. Phenol-Red is red at pH > 7. When a microbe is ...

Solution Summary

This solution lists two tests for Mannitol digestion that can be performed if you have an unknown organism. Digestion tests like the Mannitol test help determine what kind of organism you have when species and type are unknown.
