Preparation
- pH 7.0
- Prepare medium except vitamin solution, NaHCO3 und Na2S-cysteine solution under N2/CO2 gas. Add vitamin solution (filter sterilized), NaHCO3 (filter sterilized) and Na2S-cysteine solution(autoclaved) as sterile stock solutions to sterile medium after autoclaving. Adjust pH to 7.0.
- First dissolve nitrilotriacetic acid and adjust pH to 6.5 with KOH, then add minerals. Final pH 7.0 (with KOH).
- Prepare under N2 gas.
