Mix ingredients except NaHCO3 and sulfur, adjust pH to 7.5 with NaOH and autoclave. Filter-sterilize 8% NaHCO3 solution and add to the medium. Steam sulfur for 3 hr on each of 3 successive days. Distribute the medium into culture vessels containing appropriate amount of sulfur (e.g., 20 ml of medium in 120 ml serum bottles containing 0.06 g sulfur) under a stream of CO2-O2 (93:7, v/v) gas mixture, seal with butyl rubber stoppers and readjust pH to 7.5 with NaOH. Pressurize the inoculated vessel to 100 kPa CO2-O2 (93:7, v/v).
