Preparation
- pH 7.25
- Rehydrate and cultivate lyophilized cells in the complex medium recommended for the specific strain (e.g. medium 1, 220, 535 or 830). After this reactivation, cultivate on mineral medium with the appropriate carbon source.
- Adjust pH to 7.0.
- For Bacillus strains the addition of 10.0 mg MnSO4 x H2O is recommended for sporulation.
- Adjust pH to 7.3. Medium is identical with Tryptone Soya Agar (Oxoid CM 131).
- pH 7.3
- Autoclave at 121°C for 15 min.
- Final pH 7.2; adjust with crystalline K2HPO4 or KH2PO4 before adding agar. Add agar, heat medium to boiling to dissolve agar, and autoclave for 15 min at 121°C.
- First dissolve EDTA in distilled water and adjust pH to 7.0 using 2 N NaOH; then add other compounds.
