Overview
- External ontology
- mediadive.medium:P10 (source link unavailable) — BekiSolidMedium (Hydrogenovibrio crunogenus QUIMIOLITOTROFO)
- Applications
-
- Microbial cultivation
- pH range
- {'min': 6.8, 'max': 7.4}
- Notes
- MediaDive public P10 reports main-ingredient rates in g/L, but preparation starts with 1 L water, not an explicit final-volume makeup. The trace-stock dose is undisclosed ('trace'); no numeric or VARIABLE dose and no final-medium trace dilution is asserted. Existing physical state and pH are unchanged.

| 8 | Distilled water | 1 L | Preparation input: measure 1 liter distilled water = 1 L per base recipe batch, not L/L or final-medium makeup. Dissolved ingredients and the unspecified trace-stock dose are not subtracted or used to infer a final volume. |
Preparation
- Prepare the base in 1 L distilled water with NaCl, CaCl2 x 2 H2O, NaHCO3, and phosphate buffer.
- Add Na2S2O4 and prepare the Elemento traza solution from ZnSO4 x 7 H2O, FeSO4 x 7 H2O, MnCl2 x 4 H2O, CuSO4 x 5 H2O, CuCl2, Fe(III)NH4-EDTA, and (NH4)2MoO4.
- Add KNO3 and agar to complete the solid medium.
Solutions

| Ingredient | Concentration | Notes |
|---|---|---|
| ZnSO4 x 7 H2O | 0.05 G_PER_L | |
| FeSO4 x 7 H2O | 0.01 G_PER_L | |
| MnCl2 x 4 H2O | 0.05 G_PER_L | |
| CuSO4 x 5 H2O | 0.05 G_PER_L | The P10 stock table omits the unit, but the preparation text specifies 0.05 g. |
| CuCl2 | 0.01 G_PER_L | |
| Fe(III)NH4-EDTA | 0.05 G_PER_L | |
| (NH4)2MoO4 | 0.005 G_PER_L |
The inspected HTML reports Elemento traza as 'trace' with no unit or numerical dose. Removed the VARIABLE assertion: no fixed, zero or variable-range quantity is established. Stock concentrations are not final-medium trace concentrations.

The official JSON lists an Elemento traza row in the main solution with amount 0 and a blank unit, so the trace-element solution composition is preserved with a variable addition volume rather than an invented ml/L dose. |
