1 Dissolve ingredients (except carbonate, vitamins, cysteine and sulfide), then sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. After autoclaving add vitamins, cysteine and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas and carbonate from a sterile stock solution prepared under 80% N2 and 20% CO2 gas atmosphere. The vitamin solution should be sterilized by filtration. Adjust pH of the complete medium to 7.3 - 7.5, if necessary.
