1 Dissolve ingredients (except carbonate, vitamins and sulfide) and sparge medium with 80% H2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. 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 and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas (vitamins are sterilized by filtration) and carbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas mixture. Adjust pH of the complete medium to 6.8 - 7.0, if necessary.
2 After inoculation, pressurize culture vessels with sterile 80% H2 and 20% CO2 gas mixture to 1 bar overpressure.
