Aerobic metabolism of trehalose in the taxonomy of coagulase negative staphylococci.

Comparative assays demonstrated that the probability of error was 12.1% when testing the aerobic fermentation of trehalose by coagulase negative staphylococci when this carbohydrate was added to the medium prior to sterilization whereas the error was only 2.7% in media if filtered trehalose was added subsequent to steam sterilization of the medium.
