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

  1. Prepare the base in 1 L distilled water with NaCl, CaCl2 x 2 H2O, NaHCO3, and phosphate buffer.
  2. 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.
  3. Add KNO3 and agar to complete the solid medium.

2026-09-08T00:00:00-07:00 repair_mediadive_public_score30.py RESOLVED_MEDIADIVE_PUBLIC_SCORE30 MediaDive public Medium P10 provides the current Modified BekiSolidMedium agar recipe at pH 6.8-7.4. 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.
