Gélose R2A

Le milieu gélosé R2A est utilisé pour la détection des bactéries dans l'eau, notamment l'eau potable traitée. Il s'agit d'un milieu pauvre en nutriments, où une incubation prolongée et une température plus basse favorisent la croissance des bactéries stressées et traitées au chlore. La digestion enzymatique de caséine et de tissus animaux fournit des sources d'azote pour la croissance bactérienne. L'extrait de levure apporte des vitamines du complexe B et favorise la croissance. Le dextrose est un glucide fermentescible. L'amidon soluble agit comme neutralisant, tandis que le pyruvate de sodium stimule la croissance des bactéries stressées. Le phosphate dipotassique et le sulfate de magnésium heptahydraté agissent comme tampons de pH. L'agar est l'agent gélifiant. Trois formats sont disponibles : 500 g, 2 kg et 10 kg.

PRÉPARATION : Mélanger 18,2 grammes de milieu dans un litre d’eau purifiée jusqu’à ce que le mélange soit uniformément dispersé. Chauffer en remuant plusieurs fois jusqu’à dissolution complète. Autoclaver à 121 °C pendant 15 minutes.
