GranuCult^?Triple sugar iron agar

半岛bd体育手机客户端 说明

一般描述

GranuCult^?Triple sugar iron agar is recommended for the identification of Gram-negative enterobacteria. It contains lactose, sucrose, and glucose as fermentable carbohydrates. The pH indicator, phenol red, indicates the degradation of sugars to produce acids by the varying color of the medium (from red to yellow). Several species of bacteria reduce thiosulfate to hydrogen sulfide that combines with ferric ions of iron salt to produce iron sulfide, an insoluble black precipitate.

应用

GranuCult^?Triple sugar iron agar is suitable for the identification ofEnterobacteriaceaein meat, meat products, and milk.
