Study ID	ST002348
Study Title	Comparative metabolite profiling of glycolytic and sulfoglycolytic E. coli
Study Summary	Glycolytic E. coli (E. coli grown on glucose as a sole carbon source) and sulfoglycolytic E. coli (E. coli grown on the sulfosugar sulfoquinovose as a sole carbon source) were grown to mid-log phase in M9 minimal medium. Samples were harvested at mid-log phase and analysed using GC-EI-QqQ-MS.

Collection:

Collection ID:	CO002430
Collection Summary:	Cells were metabolically arrested by infusing with ice-cold PBS and washed with PBS.
Sample Type:	Bacterial cells

Treatment:

Treatment ID:	TR002449
Treatment Summary:	E. coli adapted to growth on the relevant substrate was grown on M9 minimal medium containing either Glc or SQ as a sole carbon source until mid-log phase was achieved.

Sample Preparation:

Sampleprep ID:	SP002443
Sampleprep Summary:	Cell pellets were resuspended in chilled extraction solution (500 µL) comprised of 3:1 MeOH: H2O and (13C5, 15N)valine (1 mM, 0.5 µL) and (13C6)sorbitol (1 mM, 0.5 µL) as internal standards. The suspensions were subjected to freeze-thaw cycles to facilitate lysis of the cells (30 s in liquid N2, 30 s in a dry ice/EtOH bath for 10 cycles), and shaken (9000 rpm, 10 min, 2°C). The samples were then centrifuged (12700 rpm, 5 min, 1°C). The cell lysate supernatant was transferred into glass inserts and dried. All samples were washed with MeOH (50 µL). All samples were methoximated with methoxylamine hydrochloride solution (30 mg/mL in pyridine, 20 µL) for 2 h at 37°C, followed by trimethylsilyation in BSTFA + 1% TMCS (20 µL) for 1 h at 37°C with continuous mixing. Samples were incubated at rt for 1 h prior to GC-MS analysis.
