Base de bouillon d'urée

Le bouillon de base à l'urée est un milieu liquide utilisé pour différencier les entérobactéries , en particulier les Proteus , grâce à l'activité uréasique. Ce milieu, tamponné aux phosphates di- et monopotassiques, contient de l'urée et du rouge de phénol comme indicateurs de pH. L'activité uréasique alcalinise le milieu, produisant ainsi une variation de couleur du jaune pâle au rose-rouge. L'extrait de levure fournit les sources azotées essentielles à la croissance bactérienne. Trois formats sont disponibles : 500 g, 2 kg et 10 kg.

PRÉPARATION : Mélanger 39,6 g de milieu dans un litre d’eau purifiée jusqu’à homogénéité. Chauffer en remuant régulièrement jusqu’à dissolution complète. Stériliser par filtration. NE PAS FAIRE BOUILLIR NI AUTOCLAVER.
