Bouillon MacConkey

Le bouillon MacConkey est un milieu liquide recommandé pour la culture de bactéries entériques à Gram négatif fermentant le lactose dans des échantillons d'eau, de lait et d'aliments. La digestion enzymatique de gélatine apporte des sources d'azote et de vitamines. Le lactose est la principale source de glucides. Sa fermentation produit des acides organiques qui abaissent le pH du milieu et font passer la couleur de l'indicateur pourpre de bromocrésol du violet au jaune. La bile de bœuf inhibe la croissance des organismes à Gram positif. Trois formats sont disponibles : 500 g, 2 kg et 10 kg.

PRÉPARATION : Mélanger 35 grammes de milieu dans un litre d’eau purifiée jusqu’à homogénéité. Pour tester des échantillons de 10 ml, préparer une solution doublement dosée. Répartir dans des tubes à essai contenant des tubes Durham et autoclaver à 121 °C pendant 15 minutes.
