CHEBI:2509
agar
|
20 g added after the filtered extract is made up to one liter; no soil/manure concentration or extraction yield is inferred. |
Preparation
- Add 20 g agar.
Solutions
Filtered manure extract
Dose: 1 L
| Ingredient | Concentration | Notes |
|---|---|---|
| Dry cow-manure | Extraction starting material: 50 g in 1000 ml tap water. Solids are separated before the recovered extract is used. The source does not quantify retained solids or dissolved yield; no numeric extract concentration is asserted. | |
| Tap water | 1 L | Initial extraction-water addition: 1000 ml / 1000 ml per L = 1 L, not a mass concentration or a measured recovered volume. The later make-up to one liter is a separate final-volume instruction; its additional water amount is unspecified. |
Curator-described extraction stage, not a separately accessioned stock. Composition lists preparation inputs, not retained solutes. The filtered extract is made up to one liter before agar is added. This is the prepared extract volume, not an extraction yield or a final agar-medium volume measurement.
Target organisms
No target organisms are recorded.

Removed unsupported extract-solids concentration; retained starting mass in notes; corrected initial water volume; reconciled earlier evidence scopes. No dissolved yield, density, or unspecified recovered volume inferred. |
