1 Dissolve ingredients (except sulfur, carbonate, vitamins and sulfide), then sparge medium with 80% H2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials (to 20% of volume) that contain already the appropriate amount of sulfur. For sterilization heat cultivation vessels in a water bath to 90 - 100°C for 1 - 2 hours on each of three successive days. Add vitamins and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas and carbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas mixture. The vitamin solution should be sterilized by filtration. Adjust the pH of the complete medium to 7.0. After inoculation, pressurize culture vials to 1 bar overpressure with sterile 80% H2 and 20% CO2 gas mixture.
