1 Dissolve ingredients except bicarbonate, glucose, cysteine and sulfide. Sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Add and dissolve bicarbonate, then dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add glucose, cysteine and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. Prior to use check pH of complete medium and adjust to 6.8 - 7.0, if necessary.
