Bouillon MRS aux lactobacilles

Le bouillon MRS pour lactobacilles, également appelé bouillon MRS pour lactobacilles ou bouillon LMRS, est un milieu liquide utilisé pour l'isolement sélectif et le dénombrement des lactobacilles provenant de diverses sources, notamment les matières fécales et les produits laitiers. L'extrait de bœuf et l'extrait de levure fournissent des sources d'azote, des glucides, des vitamines et des minéraux. Le dextrose est le principal glucide fermentescible. L'acétate de sodium et le citrate d'ammonium servent à la fois d'agents sélectifs et de sources d'énergie. Le phosphate de potassium agit comme tampon de pH, tandis que les sulfates de magnésium et de manganèse fournissent les cations essentiels au métabolisme bactérien. Le Tween 80 est un tensioactif qui facilite l'absorption des nutriments par les lactobacilles . Trois formats sont disponibles : 500 g, 2 kg et 10 kg.

PRÉPARATION : Mélanger 55 grammes de milieu dans un litre d’eau purifiée jusqu’à obtenir une dispersion homogène. Chauffer en remuant plusieurs fois jusqu’à dissolution complète. Autoclaver à 121 °C pendant 15 minutes.
