1 Dissolve ingredients except TYC solution, carbonate, cystein and sulfide. Sparge medium with 80% H2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic, then dispense under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Before use add TYC solution, cysteine and sulfide 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. Adjust pH of complete medium to 7.2, if necessary.
