| Study Title | Time course 2: Growth of Eggerthella lenta in defined media with some samples receiving 13C2 stable isotope labeled acetate |
| Study Type | Untargeted LC-MS |
| Study Summary | This dataset contains untargeted metabolomics analysis of supernatants from 3 strains of Eggerthella lenta grown in defined EDM1 media with varying acetate concentrations. One set of samples grew in EDM1 containing 13C2 stable isotope labeled acetate. |

| MS Comments: | Full MS-ddMS2 data was collected, an inclusion list was used to prioritize MS2 selection of metabolites from our in-house ‘local’ library, when additional scan bandwidth was available MS2 was collected in a data-dependent manner. Mass range was 60-900 mz, resolution was 60k (MS1) and 15k (MS2), centroid data was collected, loop count was 4, isolation window was 1.5 Da. In SIRM samples, deuterated internal standards were replaced with CUDA and Val-Tyr-Val to enable untargeted enrichment analysis. LC-MS/MS analysis conditions for SIRM metabolomics were identical to those used for standard untargeted metabolomics. Intra- and extracellular untargeted data generated from SIRM experiments was analyzed separately using Compound Discoverer version 3.3 (Thermo Scientific, Bremen, Germany). Samples treated with labeled compounds were always paired with matched samples treated with unlabeled compounds in order to correct for naturally occurring isotope abundances. Unlabeled samples were used for compound detection and formula assignment via isotope pattern-based prediction, spectral library matches, or mass lists matches. The isotope patterns and formulas from the sample files then served as a reference for the detection of potential isotopologues per compound in the labeled sample type.
