A-1 Moyen

A-1 Medium

A-1 Medium is used for the detection of fecal coliforms in drinking water, treated wastewater, seawater, and beverages. Enzymatic Digest of Casein provides nitrogenous sources and vitamins. Lactose and Salicin are the carbohydrate sources providing energy for bacterial growth. Sodium Chloride maintains the osmotic balance. Triton X-100 is a surfactant improving nutrient uptake by the bacteria. There is a choice of 3 sizes - 500g, 2kg, and 10kg.

A-1 Moyen

Le milieu A-1 est utilisé pour la détection des coliformes fécaux dans l'eau potable, les eaux usées traitées, l'eau de mer et les boissons. La digestion enzymatique de la caséine apporte des sources d'azote et de vitamines. Le lactose et la salicine sont les sources de glucides fournissant l'énergie nécessaire à la croissance bactérienne. Le chlorure de sodium maintient l'équilibre osmotique. Le Triton X-100 est un tensioactif qui améliore l'absorption des nutriments par les bactéries. Trois formats sont disponibles : 500 g, 2 kg et 10 kg.

PRÉPARATION : Mélanger 31,5 grammes de milieu dans un litre d’eau purifiée jusqu’à dispersion homogène. Chauffer en remuant plusieurs fois jusqu’à dissolution complète. Répartir dans des tubes à essai avec des tubes Durham et autoclaver à 121 °C pendant 10 minutes.
