| 1 Dissolve ingredients except carbonate, pyruvate, yeast extract, vitamins 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. Add pyruvate, yeast extract, vitamins and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas atmosphere and carbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas mixture. Stock solutions of pyruvate and vitamins are sterilized by filtration. After completing the medium adjust pH to 6.8-7.0 with a sterile anoxic stock solution of Na2CO3 (5% w/v), if necessary. | |||||
