Preparation

  1. Dissolve ingredients except for methanol and dithiothreitol. Adjust pH to 7.5 with 1 N NaOH and sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic. Distribute medium under 100% N2 gas atmosphere into anoxic Hungate-type tubes or serum vials to 30% of their volume and autoclave. After sterilization add methanol from a sterile anoxic stock solution (15% v/v) autoclaved under 100% N2 gas atmosphere and dithiothreitol from an anoxic stock solution sterilized by filtration. Before use check the pH of the complete medium and adjust it to 7.6 - 7.8, if necessary.
  2. After inoculation, add sterile 80% H2 and 20% CO2 gas mixture to 0.5 bar overpressure. After growth becomes visible overpressure of 80% H2 and 20% CO2 gas mixture can be increased to 1 bar.
  3. Note: Use 10% (v/v) as inoculum.
  4. Dissolve 50 mg haemin in 1 ml 1 N NaOH; make up to 100 ml with distilled water and filter sterilize. Store refrigerated.
  5. Dissolve 0.1 ml of vitamin K1 in 20 ml 95% ethanol and filter sterilize. Store refrigerated in a brown bottle.
