 Prior to analysis, samples were centrifuged at \SI{2990}{\gforce} for
-\SI{20}{\minute} at \SI{4}{\degreeCelsius} to clear any debris. 5 uL of 100/3 mM
-DSS-D6 in deuterium oxide (Cambridge Isotope Laboratories) were added to 1.7 mm
-NMR tubes (Bruker BioSpin), followed by 45 uL of media from each sample that was
-added and mixed, for a final volume of 50 uL in each tube. Samples were prepared
-on ice and in predetermined, randomized order. The remaining volume from each
-sample in the rack (approx. 4 uL) was combined to create an internal pool. This
-material was used for internal controls within each rack as well as metabolite
-annotation.

 MHz using a 5-mm TXI cryogenic probe and TopSpin software (Bruker BioSpin).
