Collection:
Collection ID: | CO001490 |
Collection Summary: | The WT, fnr, arcA and ihf mutants were grown in a bioreactor in glucose minimal media under anaerobic fermentation conditions at 37 degrees Celsius and 150 rpm. The samples were harvested during its exponential phase of growth for three biological and two technical replicates (n=6). The metabolites were extracted using the Methanol-Chloroform-Water method. Detailed sample collection protocol is described in “Extraction_protocol_msi.pdf”. |

Sampleprep ID: | SP001503 |
Sampleprep Summary: | Samples were extracted from the Wildtype, fnr, arcA and ihf mutants grown in a bioreactor anaerobically in glucose minimal media at 37 degrees Celsius and 150 rpm. The metabolites were extracted using the Methanol-Chloroform-Water method. The samples were spiked with an equal volume of 13C-labelled internal standard taken from the same batch at an earlier stage to prevent to account for losses due to metabolite degradation and to enable robust quantification circumventing the ion-suppression effects. |
