Chromatography Summary:Bacterial supernatant were analyzed via hydrophilic interaction liquid chromatography (HILIC) coupled to a Thermo Q-Exactive HF high resolution mass spectrometer. Each sample was analyzed in both positive and negative ionization modes (ESI+, ESI-) via subsequent injections. 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. Metabolomics data was processed using MS-DIAL v4.60 (https://www.nature.com/articles/s41587-020-0531-2) and queried against a combination of our in-house MS2 library (https://www.nature.com/articles/s41586-021-03707-9) and MassBank of North America, the largest freely available spectral repository (https://doi.org/10.1002/mas.21535). Annotations were scored using guidelines from the metabolomics standards initiative (https://www.nature.com/articles/nbt0807-846b). Features were excluded from analysis if peak height was not at least 5-fold greater in one or more samples compared to the procedural blank average.
