Preparation
- Dissolve ingredients except cysteine, carbonate and sulfide. Sparge medium with 80% H2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Add and dissolve cysteine, then dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials to 30% of their volume and autoclave. Add carbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas mixture and sulfide from a sterile anoxic stock solution prepared under 100% N2 gas. Prior to use check pH of complete medium and adjust to 6.8 - 7.0, if necessary.
- Note: After growth has started add sterile 80% H2 and 20% CO2 gas mixture to 0.5 - 1 bar overpressure.
