1 Dissolve ingredients (except sulfur, peptone, yeast extract, and sulfide), sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Adjust pH to 7.2 - 7.4, then dispense medium under the same gas atmosphere into anoxic Hungate-type tubes or serum vials containing already the appropriate amount of sulfur and autoclave at 110°C for 20 min. Add peptone, yeast extract and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. The pH of the complete medium should be 7.5.
