|Lithium chloride·6H2O||5 g|
Autoclave 15 min at 121°C. Final pH, 7.0 ± 0.2. If desired for immediate use, maintain melted medium at 48-50°C before adding enrichment. Otherwise, store solidified medium at 4 ± 1°C up to 1 month. Melt medium before use.
Bacto EY tellurite enrichment.
Aseptically add 5 ml prewarmed (45-50°C) Bacto EY tellurite enrichment to 95 ml melted base. Mix well (avoiding bubbles) and pour 15-18 ml portions into sterile 15 × 100 mm petri dishes. The medium must be densely opaque. Dry plates before use. Store prepared plates at 20-25°C for up to 5 days.
