Application
General description
This culture medium contains lactose, whose degradation to acid is indicated by the pH indicator phenol red, which changes its color to yellow. The indicator exhibits a pink-red color in the alkaline range.
In this highly selective culture medium, the increased growth of accompanying microorganisms is considerably prevented by raising the concentration of brilliant green.
The growth of Salmonella is improved by the richer nutrient base, but Salmonella Typhi and Shigella spp. are largely inhibited by brilliant green.
Most Salmonellae are not able to ferment either lactose or sucrose. The sucrose contained in this medium allows identification of accompanying, weakly lactose-positive or lactose-negative, but sucrose-positive microorganisms. Phenol red serves as a pH indicator and yields a yellow color as a result of in the fermentation of lactose and/or sucrose in the medium. Agar is the solidifying agent.
Other Notes
The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.
