1 Dissolve ingredients (except sulfur, carbonate, vitamins, growth-stimulating factors and Na-dithionite), boil medium for 1 min, then cool to room temperature under 80% H2 and 20% CO2 gas atmosphere. Adjust pH to 6.0 and dispense under 80% H2 and 20% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials which contain already the appropriate amount of sulfur, only to 30% of their volume to allow for a large head space. Autoclave at a temperature of 110°C for 20 min! Add vitamins and growth-stimulating factors from sterile anoxic stock solutions prepared under 100% N2 gas and carbonate and Na-dithionite from sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas atmosphere. Vitamins and Na-dithionite are sterilized by filtration. Adjust pH of the complete medium to 6.0, if necessary.
2 After inoculation use 1 bar overpressure of sterile 80% H2 and 20% CO2 gas mixture.

1 Dissolve NaHCO3 in water and make the solution anoxic by sparging with 80% N2 and 20% CO2 gas mixture. Then dissolve the Na-dithionite and filter sterilize the solution into anoxic Hungate tubes. Store the prepared solution in the dark and refrigerated. Prepare only small amounts of stock solution, as Na-dithionite decomposes rapidly.
