1 Dissolve ingredients (except vitamins, cysteine and sulfide), sparge medium with 80% H2 and 20% CO2 gas mixture to reach a pH below 6 (at least 30 min), then dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials to 30% of their volume and autoclave. After sterilization add cysteine and sulfide from sterile anoxic stock solutions autoclaved under 100% N2 gas atmosphere. Vitamins are prepared under 100% N2 gas atmosphere and sterilized by filtration. Adjust pH of final medium to 5.5 - 5.7.
2 For incubation use sterile 80% H2 and 20% CO2 gas mixture at two atmospheres of pressure.
