1 Dissolve ingredients except carbonate, vitamins, and sulfide, then sparge medium with 100% CO2 gas for 30 - 45 min to make it anoxic. Dissolve carbonate and adjust pH to 6.7, then dispense medium under the same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add vitamins and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. Vitamins should be sterilized by filtration.
