Gélose DRBC

La gélose DRBC, basée sur la formulation originale de King, Hocking et Pitt, est utilisée pour le dénombrement des levures et moisissures viables dans la bière et autres produits à forte activité hydrique. L'agent antifongique dichloran limite la croissance des champignons mucoréiques et réduit la taille des colonies d'autres champignons prolifératifs. Le rose Bengale et le chloramphénicol agissent comme agents sélectifs contre les bactéries, contribuant ainsi à réduire la taille des colonies de moisissures à croissance rapide. La digestion enzymatique de tissus animaux et la peptone fournissent des sources d'azote, tandis que le glucose est le glucide fermentescible. L'agar est l'agent gélifiant. Trois formats sont disponibles : 500 g, 2 kg et 10 kg.

PRÉPARATION : Mélanger 31,6 g de milieu dans un litre d’eau purifiée jusqu’à homogénéité. Chauffer en remuant plusieurs fois jusqu’à ébullition pour dissoudre complètement. Autoclaver à 121 °C pendant 15 minutes. Veiller à ne pas exposer le milieu à la lumière.
