NBRC Medium 972 uses 900 ml Distilled water in the main base plus 100 ml water in the sodium-sesquicarbonate stock. |
Preparation
- Suspend Nutrient Broth (OXOID), NaCl, and optional agar in 900 ml distilled water.
- Autoclave the nutrient-broth NaCl base.
- Sterilize the 100 ml NaHCO3 and Na2CO3 sodium-sesquicarbonate stock separately.
- Aseptically add the sterile sodium-sesquicarbonate stock to the sterile base.
