Modified medium for the oxidation-fermentation test in the identification of marine bacteria.

Using the medium of ZoBell as a basal formulation, we developed a medium to determine the oxidative-fermentative metabolism in marine bacteria. Different oxidative and fermentative collection strains, as well as a group of unidentified marine bacteria, were tested on modified ZoBell medium and other conventional media. In general, superior results were obtained with the modified ZoBell medium since it supported good bacterial growth and gave more clear-cut oxidative reactions.
