摘要:
Chromogenic substrate member for identifying Escherichia coli bacteria. It comprises a growing medium for said bacteria and container means (1) for the growing medium (4) and a liquid sample to be tested. The container means also contains a chromogenic reagent compound consisting in 8-hydroxyquinoline-β-D glucuronide and an activator compound consisting in X-glucuronide where X is selected from the group consisting in alkyl, aryl or indoxyl radical, the halogeno substitutes and the nitro substitutes thereof.
摘要:
The invention concerns a novel chromogenic medium for isolating Staphylococcus aureus, characterised in that it comprises in a culture medium of Staphylococcus aureus at least one of the following two chromogenic agents: 5-bromo 6-chloro 3-indoxyl phosphate and 5-bromo 4-chloro 3-indoxyl glucoside and it further contains deferoxamine.
摘要:
The invention concerns a culture medium for isolating Vibrio bacteria, characterised in that it comprises, in a Vibrio culture medium, at least a chromogenic agent selected among the beta -glucosidase substrates and the beta -galactosidase substrates.

摘要:
A method for revealing the presence or absence of a particular microorganism strain in a culture medium, wherein at least two strain enzyme substrate chromogens are added to the culture medium, said chromogens being selected so that the presence of said strain in the culture medium is revealed by a third colour.
摘要:
A method for revealing the presence or absence of a particular microorganism strain in a medium, wherein at least one strain enzyme substrate chromogen and at least one compound selected from a high-concentration carbohydrate are added to the culture medium so that a derived colour differing from the basic colour of the chromophore is obtained once the chromogen has been hydrolysed.
摘要:
La présente invention concerne un milieu d'isolement pour l'identification de la bactérie Salmonella , caractérisé en ce qu'à un support de culture contenant des peptones, on ajoute un polyol métabolisable par Salmonella et un indicateur de pH réagissant à l'acidification. La présente invention se rapporte en outre à un procédé d'identification de la bactérie Salmonella à partir dudit milieu.
