Application

Aureus ChromoSelect Agar Base is recommended for the isolation and enumeration of coagulase positive Staphylococcus aureus from environment samples. Coagulase positive S. aureus gives brown black colonies where as S. epidermidis gives yellow- slightly brownish colonies.

Preparation Note

Suspend 63.1 g in 950 ml distilled water. Boil to dissolve the medium completely. Sterilise by autoclaving at 121°C for 15 min. Cool to 50°C and aseptically add 50 ml concentrated Egg Yolk Tellurite Emulsion (Cat. No. 75208). Mix well and pour into sterile petri plates.

Footnote

We offer two media types: the superior granulated GranuCult® and the cost-efficient powdered NutriSelect® culture media, depending on your needs.
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.
