1 Mix ingredients, except sulfur and Na2S x 9H2O, and adjust pH to 6.0 with H2SO4. Sterilize the medium by filtration. Steam sulfur for 3 hr on each of 3 successive days. Neutralize Na2S x 9H2O as a 5% solution, and autoclave under a N2 atmosphere. Distribute the medium and sulfur into culture vessels (e.g., 20 ml of the medium in 120 ml serum bottles) under a stream of H2-CO2 (4:1, v/v) gas mixture and seal with butyl rubber stoppers. Prior to inoculation, add the sterile Na2S x 9H2O solution, and readjust pH to 6.0 with sterile 1 N H2SO4. Pressurize the inoculated bottles to 200 kPa H2-CO2 (4:1, v/v).
