Preparation

  1. Mix 1.0 L MJ(-N) synthetic seawater, NH4Cl, NaNO3, and Yeast extract thoroughly; distribute the medium into culture vessels under a N2-CO2 (4:1, v/v) gas mixture, seal with butyl rubber stoppers, and autoclave.
  2. After cooling, add 5.0 ml/L 8% NaHCO3 solution and 10.0 ml/L 5% Na2S x 9 H2O solution that were filter-sterilized or autoclaved and stored anaerobically.
  3. Pressurize the culture vessels to 200 kPa N2-CO2 (4:1, v/v) and check the final pH at 6.0-6.5.
  4. MJ(-N) synthetic seawater can be replaced with a commercial synthetic seawater such as Jamarin S. For strain JCM 15506, inoculate with a 5-10% inoculum.
