Preparation
- Mix ingredients except sulfur and Na2S x 9H2O, adjust pH to 5.0 and autoclave under a N2 atmosphere. Steam sulfur for 3 hr on each of 3 successive days. Distribute the medium into culture vessels (e.g., 20 ml in 120 ml serum bottles) containing sulfur under a stream of a H2-CO2 (4:1, v/v) gas mixture and seal with butyl rubber stoppers. Prior to inoculation, add 5% Na2S x 9H2O (autoclaved and stocked under a N2 atmosphere) to the medium. Readjust pH to 5.0 - 5.3. Pressurize the inoculated bottles to 200 kPa H2-CO2 (4:1, v/v).
