GranuCult(R) Triple sugar iron agar

Descrição detalhada : GranuCult(R) 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.
