The exact recipe specifies albumin, not LB broth. Remove only the three reviewed LB supplier nodes and restore albumin at its source-defined preparation stage. Genuine yeast extract and unrelated annotations are preserved. Withdraw the unsupported high_metal classification, not replace it with false. Its schema definition requires total metal concentration >=1049.84 mM. Source quantities include milligram batch inputs, one liter of water, and later stocks; a final-volume denominator and all molecular-form conversions are not established. The former g/L fields cannot support this classification.

Preparation
- Mix components except yeast extract, bovine serum albumin and Na2S·9H2O.
- Bring to a boil for 5-10 sec and flush with N2.
- Adjust pH to 7.6 at 80-90C.
- After cooling to room temperature, dispense the medium into serum bottles under a N2 atmosphere, seal with butyl rubber stoppers and autoclave.
- Separately autoclave yeast extract as a 10% solution and neutralized Na2S·9H2O as a 5% solution under a N2 atmosphere.
- Filter-sterilize bovine serum albumin as a 10% (w/v) solution under a N2 atmosphere.
- Before inoculation, aseptically and anaerobically add the yeast extract, bovine serum albumin and neutralized Na2S·9H2O solutions.
Solutions
10% yeast extract solution
| Ingredient | Concentration | Notes |
|---|---|---|
| Yeast extract (BD-Difco) | Properties: Undefined component Source batch input: 1 g. Final preparation volume is not independently established; the unsupported g/L assertion is withdrawn, not replaced by an assumed one-liter concentration. This is the contribution specified for the receiving medium batch, not the mass for preparing an unspecified volume of stock. |
Separate stock preparation added aseptically and anaerobically under N2 before inoculation. The source table mass is its contribution to the receiving batch, not a mass for preparing an unspecified stock volume. The stock percentage basis and fixed dose are unspecified.
10% (w/v) bovine serum albumin solution
Dose: 0.01 L
| Ingredient | Concentration | Notes |
|---|---|---|
| Bovine serum albumin | 10 PERCENT_W_V | Source batch input: 1 g. Final preparation volume is not independently established; the source batch amount is retained without asserting a final concentration. This is the contribution specified for the receiving medium batch, not the mass for preparing an unspecified volume of stock. Explicit albumin-stock strength is 10% (w/v) = 10 g per 100 ml = 100 g/L. This is not the receiving-medium concentration. |
Separate stock preparation added aseptically and anaerobically under N2 before inoculation. The source table mass is its contribution to the receiving batch, not a mass for preparing an unspecified stock volume.
Derived receiving-batch dose: source contribution 1 g / explicit stock strength (10 g / 0.1 L = 100 g/L) = 0.01 L (10 ml). Both inputs describe this recipe's separately filtered albumin stock. No final-medium volume is needed or inferred; the dose is calculated, not directly printed in the source.
5% neutralized sodium sulfide nonahydrate solution
| Ingredient | Concentration | Notes |
|---|---|---|
| Na2S・9H2O | Role: Reducing agent; Properties: Defined component, Simple component, Inorganic compound 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. This is the contribution specified for the receiving medium batch, not the mass for preparing an unspecified volume of stock. |
Separate stock preparation added aseptically and anaerobically under N2 before inoculation. The source table mass is its contribution to the receiving batch, not a mass for preparing an unspecified stock volume. The stock percentage basis and fixed dose are unspecified.
