Preparation

  1. Mix all ingredients except vitamin solution and Na2S·9H2O.
  2. Adjust pH to 7.0 with H2SO4.
  3. Autoclave the medium under a N2 atmosphere.
  4. Autoclave Na2S·9H2O separately as a 5% solution under N2.
  5. Filter-sterilize the vitamin solution.
  6. Anaerobically add filter-sterile vitamin solution and sterile Na2S·9H2O.
