1 Dissolve ingredients except carbonate, succinate and sulfide, then sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Dispense medium under the same gas atmosphere into anoxic Hungate-type tubes and autoclave. Add succinate (sterilized by filtration) 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 mixture. Prior to use adjust pH of complete medium to 7.2 - 7.5. | |||||
2 Note: Dispense medium into anoxic Hungate-type tubes or serum vials only to 30% of their volume to allow a large head space. |
