Role: Solvating media; Properties: Inorganic compound, Defined component, Simple component [Merged 3 duplicates: 500.0, 1.0, 1.0] Source water batch input: 500 ml = 0.5 L. This is not a measured final volume. The earlier duplicate-summing note is superseded: it combined separate preparation scopes and source units. This node carries only the batch input at the cited source row; other occurrences are separate scoped ingredients.

sulfuric acid
Role: Mineral source; Properties: Defined component, Inorganic compound, Solution Source pH-adjustment reagent with no fixed dose. Removed the unsupported VARIABLE placeholder.

Preparation

  1. Mix ingredients, except sulfur and Na2S·9H2O, and adjust pH to 6.0 with H2SO4.
  2. Sterilize the medium by filtration.
  3. Steam sulfur for 3 hr on each of 3 successive days.
  4. Neutralize Na2S·9H2O as a 5% solution, and autoclave under a N2 atmosphere.
  5. Distribute the medium and sulfur into culture vessels (e.g., 20 ml of the medium in 120 ml serum bottles) under a stream of H2-CO2 (4:1, v/v) gas mixture and seal with butyl rubber stoppers.
  6. Prior to inoculation, add the sterile Na2S·9H2O solution, and readjust pH to 6.0 with sterile 1 N H2SO4.

Na2S・9H2O Role: Reducing agent; Properties: Inorganic compound, Defined component, Simple component Source batch input: 0.5 g. Final preparation volume is not independently established; the unsupported g/L assertion is withdrawn, not replaced by an assumed one-liter concentration.
