1 Dissolve ingredients except bicarbonate, pyruvate, vitamins and reducing agents, then adjust pH of solution to 7.0 with NaOH. Sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic, then dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add pyruvate, vitamins, cysteine and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas and bicarbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas mixture. Vitamins should be sterilized by filtration. Adjust pH of complete medium to 7.0, if necessary.
