1 Dissolve ingredients except sulfur, carbonate, hydrogen phosphate, thiosulfate, and vitamins, then sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. 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 hydrogen phosphate, thiosulfate, and vitamins 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. Stock solutions of thiosulfate and vitamins should be sterilized by filtration. The pH of the complete medium should be 6.5 - 6.8.
