Preparation

  1. Dissolve ingredients except bicarbonate, vitamins, cysteine, and sulfide, then sparge medium with 80% H2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Add and dissolve bicarbonate and adjust pH to 6.5. Then dispense medium under 80% H2 and 20% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials to 30% of their volume and autoclave. Add vitamins, cysteine, and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. The vitamin solution should be sterilized by filtration. Before use, check the complete medium's pH and adjust it to 6.8 - 7.0, if necessary.
  2. After growth has started and the culture is becoming turbid add sterile 80% H2 and 20% CO2 gas mixture to 0.5 - 1 bar overpressure.
  3. First dissolve FeCl2 in the HCl, then dilute in water, add and dissolve the other salts. Finally make up to 1000.00 ml.
