1 Mix ingredients except sulfur, NaHCO3 and Na2S x 9H2O, adjust pH to 6.5 and autoclave. Filter-sterilize 8% NaHCO3 solution and add to the medium. Steam sulfur for 3 hr on each of 3 successive days. Separately autoclave 5% Na2S x 9H2O solution under a N2 atmosphere. Aseptically distribute the medium into culture vessels containing appropriate amount of sulfur (e.g., 20 ml culture medium in 120 ml serum bottle containing 0.24 g sulfur) under a 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 6.5, if necessary. Pressurize the inoculated bottles to 200 kPa H2-CO2 (4:1, v/v). |
