Preparation

  1. Mix ingredients except vitamin solution, sulfur, and Na2S·9H2O.
  2. Adjust pH to 7.0.
  3. Autoclave under a N2 atmosphere.
  4. Filter-sterilize the vitamin solution.
  5. Sterilize sulfur by autoclaving for 60 minutes at 105 C on each of 3 successive days.
  6. Neutralize Na2S·9H2O as a 5% solution and autoclave under N2.
  7. Before inoculation, aseptically and anaerobically add vitamin, sulfur, and Na2S·9H2O.
