1 Dissolve ingredients (except bicarbonate, yeast extract, fructose, vitamins, and reducing agents), sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic and adjust pH to 5.0. Dispense medium under the same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave at 121°C for 15 min. Add yeast extract, fructose, vitamins (sterilized by filtration), cysteine, and sulfide from sterile stock solutions prepared under a 100% N2 gas atmosphere and bicarbonate from a sterile stock solution prepared under an 80% N2 and 20% CO2 gas atmosphere. Adjust the pH of the complete medium to 5.9!
