Abstract
The invention relates to a growth medium allying a fluorogenic substrate and a pH-sensitive fluorophore, in particular the combination of 4-methylumbelliferone (4-MU) and derivatives of fluorescein. This growth medium is used for the detection by fluorescence of microorganisms by coupling the fluorescence measurements relating to the pH-sensitive fluorophor and the fluorescence measurements relating to the activation of the fluorogenic substrate(s) by the microorganisms.
