Descrizione

Descrizione generale

GranuCult^® prime Salmonella Shigella (SS) Agar is a nutrient rich medium which is designed to isolate and differentiate Salmonella spp. from food, animal feed, water, and other test samples.
The presence of brilliant green, ox bile, high concentrations of thiosulfate and citrate largely inhibits the accompanying flora and swarming of Proteus spp, while allowing the growth of Salmonella spp. The synergistic reaction between thiosulfate and iron salt present in the media enables the growth of H₂S positive black color colonies.
Lactose present in the media differentiates between the lactose positive and lactose negative microorganisms. Lactose fermenting microbes form an acid which is indicated by forming red colonies due to the presence of a pH indicator, neutral red. Peptones provide nitrogen, vitamins, amino acids, and minerals for growth and agar acts as a solidifying agent.
