Bouillon Letheen, modifié

Le bouillon de base Letheen modifié est un milieu liquide utilisé pour déterminer l'activité antimicrobienne des composés d'ammonium quaternaire. La lécithine, le Tween 80 et le bisulfite de sodium neutralisent les composés d'ammonium quaternaire, les phénols et le formol présents dans les produits cosmétiques. La peptone de viande, l'extrait de bœuf, l'extrait de levure et la digestion enzymatique de caséine apportent des composés azotés, des glucides, des vitamines et des minéraux. Le chlorure de sodium maintient l'équilibre osmotique. Trois formats sont disponibles : 500 g, 2 kg et 10 kg.

PRÉPARATION : Mélanger 42,8 g de milieu dans un litre d’eau purifiée jusqu’à obtenir une dispersion homogène. Chauffer en remuant plusieurs fois et faire bouillir pendant une minute pour dissoudre complètement. Répartir et autoclaver à 121 °C pendant 15 minutes.
