1 Dissolve ingredients except carbonate, methanol and sulfide, then sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic. Add and dissolve carbonate and adjust pH to 9.0 - 9.2, then dispense medium under 100% N2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Prior to inoculation add methanol (50% v/v solution) and sulfide from anoxic stock solutions autoclaved under 100% N2 gas. Adjust pH of complete medium to 9.2 - 9.4.
