Preparation
- Add components to distilled water and bring volume to 1.0 L. Adjust pH to 7.5 with KOH, distribute the medium into culture vessels (e.g., 5 ml of the medium in the Hungate tubes) under a N2--CO2 (4:1, v/v) gas mixture, seal with butyl rubber stoppers and autoclave. After cooling, add per literthe following solutions from anaerobic stocks (autoclaved or*filter--sterilized):

| Ingredient | Concentration | Notes |
|---|---|---|
| Distilled water | Role: Solvating media; Properties: Defined component, Inorganic compound, Simple component Water is the makeup reagent for the explicitly stated 1.0 L basal stage, not a fixed 1 L water input or a final supplemented-medium volume. Its actual addition amount is unspecified. | |

This is the explicitly made-up basal preparation before later supplements. Composition rates apply at the 1.0 L makeup stage only. No fixed dose of the subsequently titrated/heated basal preparation or final supplemented-medium volume is asserted.
