1 Dissolve ingredients except carbonate, vitamins and sulfide. Sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic. Dispense medium under the same gas atmosphere into anoxic Hungate-type tubes and autoclave. Add vitamins and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas (vitamins are sterilized by filtration) and carbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas mixture. Prior to use adjust pH of complete medium to 7.5 - 8.0.
