1 Dissolve ingredients except bicarbonate, yeast extract, vitamins and sulfide, then sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic. Dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add yeast extract, vitamins (sterilized by filtration) and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas atmosphere and bicarbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas mixture. Neutralize the sodium sulfide with sterile H2SO4 (see medium 29). After completing the medium adjust pH to 6.8-7.0. Inoculated vessels are pressurized with sterile carbon monoxide gas to 2 bar overpressure.
