1 Dissolve all ingredients except cysteine, carbonate, starch and vitamins. Sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic, add cysteine and adjust pH to 7.5, then dispense medium under 100% N2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add starch 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 atmosphere. Vitamins should be sterilized by filtration. Adjust pH of complete medium to 9.3 - 9.5, if necessary.
