Mix components except Na2S·9H2O and adjust pH to 6.7. Distribute the medium into culture vessels (e.g., 20 ml in 120 ml serum bottles) under a gas stream of H2-CO2 (4:1, v/v), seal with butyl rubber stoppers and autoclave. Separately autoclave 3% Na2S·9H2O solution under a N2 gas atmosphere. Prior to inoculation, reduce the medium by the addition of the Na2S·9H2O solution. Pressurized the inoculated culture vessels to 200 kPa H2-CO2 (4:1, v/v).
