Preparation
- Dissolve ingredients except vitamins, bicarbonate and malate. Adjust pH to 6.5, dispense medium in culture vessels and autoclave. Prior to inoculation add vitamins, bicarbonate and malate from stock solutions sterilized by filtration. Adjust pH of complete medium to 6.7 - 6.9.
- First dissolve FeCl2 in the HCl, then dilute in water, add and dissolve the other salts. Finally make up to 1000.00 ml.
