| 1 Dissolve ingredients except carbonate, thiosulfate, cysteine and sulfide. Sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic, then dispense under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add thiosulfate, cysteine and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas and carbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas atmosphere. Stock solutions of thiosulfate and vitamins should be sterilized by filtration. The pH of the complete medium should be 7.2 - 7.4. | |||||
