 | | In addition, at least one other activity is assayed, namely an activity which is expressed by all or some Listeria such as a saccharidase, a phosphatase or an aminopeptidase, which enhances the contrast between the color of colonies of Listeria monocytogenes and that of colonies of other species belonging to the same genus. |
 | | According to a preferred embodiment, the other enzyme activity expressed by all or some Listeria species is a saccharidase, a phosphatase or an aminopeptidase. |
 | | More precisely, the substrate which detects the other activity such as a saccharidase, a phosphatase or an aminopeptidase is at a concentration of between 10 mg/l and 500 mg/l, preferably between 50 and 300 mg/l, and more preferably still between 100 and 200 mg/l. |
