Preparation

  1. Mix ingredients, bring to a boil and cool under a H2-CO2 (4:1, v/v) gas mixture. Slowly add 10 ml 5% Na2S x 9H2O solution to the medium, wait for the medium to become colorless, then adjust pH to 7.0 with NaOH. Distribute medium into culture vessels under the same gas mixture, seal with butyl rubber stoppers and autoclave. Before inoculation, aseptically and anaerobically add per liter the following solutions from anaerobic stocks (autoclaved and stored under a N2 atmosphere):
  2. Pressurize the inoculated culture vessels to 200 kPa H2-CO2 (4:1, v/v).
