4-Methylumbelliferyl-alpha-D-glucoside, the fluorogenic substrate of alpha-glucosidase, was used as a selective marker to develop a differential medium for Enterobacter sakazakii. This bacterium showed strong fluorogenic characteristics clearly distinguishable from other microorganisms. On the basis of reducing background noise, an optimum
