1 Dissolve ingredients (except bicarbonate, cysteine, methanol, vitamins and sulfide), sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic, then add solid bicarbonate and cysteine and equilibrate the medium with the gas mixture to reach a pH of 7.0. Dispense medium under 80% N2 and 20% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. To the autoclaved medium add methanol (50% v/v solution), vitamins and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. Vitamins should be sterilized by filtration. Adjust pH of complete medium to 7.0 - 7.2, if necessary.
