Notes

Source: KOMODO ModelSEED | ID: 125 | DSMZ Medium: 125 (mediadive.medium:125) | Aerobic: No Common basal table for two source-listed alternative preparations: add 5 ml methanol or incubate under methane-air (4:1). Neither alternative is selected or combined here. The retained g/L entries are provider-declared basal-table rates, not independently verified final concentrations after choosing a carbon preparation. The 1000 ml water entry is a batch input, not a measured final volume. Methanol purity, final volume, methanol final concentration and dissolved methane concentration remain unspecified. Existing chemical mappings and strain-modified source-duplicate links are preserved, not newly validated by this recipe evidence. The imported 'Aerobic: No' annotation is retained as unverified metadata, not used to select either preparation.

Relationship
SUPPLEMENTED_VARIANT
Description
Source-listed methanol alternative to methane-air incubation; common basal table unchanged.
Modifications
- Add 5 ml methanol to the source's common basal batch; do not combine this option with the methane-air alternative.
- This is a batch addition, not 5 ml/L or 0.5% final-medium methanol; final volume and methanol purity are not specified.
Purpose
Represent the source-listed methanol preparation without choosing it for every use.

  variants[0] (Methanol preparation option): Source-listed alternatives, not simultaneous components. Common basal table for two source-listed alternative preparations: add 5 ml methanol or incubate under methane-air (4:1). Neither alternative is selected or combined here. The retained g/L entries are provider-declared basal-table rates, not independently verified final concentrations after choosing a carbon preparation. The 1000 ml water entry is a batch input, not a measured final volume. Methanol purity, final volume, methanol final concentration and dissolved methane concentration remain unspecified.

Description
Source-listed incubation alternative to methanol addition; common basal table unchanged.
Modifications
- Incubate under methane-air (4:1) as the alternative to adding methanol.
- The gas ratio is not a liquid ingredient dose or a dissolved methane concentration; no gas pressure or total volume is specified.
Purpose
Represent the source-listed methane-air alternative without asserting a dissolved carbon concentration.
