#METABOLOMICS WORKBENCH bcdefelice_20230825_102524 DATATRACK_ID:4248 STUDY_ID:ST002833 ANALYSIS_ID:AN004628 PROJECT_ID:PR001774 VERSION 1 CREATED_ON August 28, 2023, 2:26 pm #PROJECT PR:PROJECT_TITLE Resource competition predicts assembly of in vitro gut bacterial communities PR:PROJECT_SUMMARY Microbiota dynamics arise from a plethora of interspecies interactions, PR:PROJECT_SUMMARY including resource competition, cross-feeding, and pH modulation. The individual PR:PROJECT_SUMMARY contributions of these mechanisms are challenging to untangle, especially in PR:PROJECT_SUMMARY natural or complex laboratory environments where the landscape of resource PR:PROJECT_SUMMARY competition is unclear. Here, we developed a framework to estimate the extent of PR:PROJECT_SUMMARY multi-species niche overlaps by combining metabolomics data of individual PR:PROJECT_SUMMARY species, growth measurements in pairwise spent media, and mathematical models. PR:PROJECT_SUMMARY When applied to an in vitro model system of human gut commensals in complex PR:PROJECT_SUMMARY media, our framework revealed that a simple model of resource competition PR:PROJECT_SUMMARY described most pairwise interactions. By grouping metabolomic features depleted PR:PROJECT_SUMMARY by the same set of species, we constructed a coarse-grained consumer-resource PR:PROJECT_SUMMARY model that predicted assembly compositions to reasonable accuracy. Moreover, PR:PROJECT_SUMMARY deviations from model predictions enabled us to identify and incorporate into PR:PROJECT_SUMMARY the model additional interactions, including pH-mediated effects and PR:PROJECT_SUMMARY cross-feeding, which improved model performance. In sum, our work provides an PR:PROJECT_SUMMARY experimental and theoretical framework to dissect microbial interactions in PR:PROJECT_SUMMARY complex in vitro environments.

Frozen stocks were CO:COLLECTION_SUMMARY streaked onto BHI-blood agar plates (5% defibrinated horse blood in 1.5% w/v CO:COLLECTION_SUMMARY agar). Resulting colonies were inoculated into 3 mL of Brain Heart Infusion CO:COLLECTION_SUMMARY (BHI) (BD #2237500) or modified Gifu Anaerobic Medium (mGAM) (HyServe #05433) in CO:COLLECTION_SUMMARY test tubes. All culturing werewas performed at 37 °C without shaking in an CO:COLLECTION_SUMMARY anaerobic chamber (Coy). To minimize potential physiological changes from CO:COLLECTION_SUMMARY freeze-thaw cycles and changes in growth medium, cultures were diluted 1:200 CO:COLLECTION_SUMMARY every 48 h for 3 passages before growth or metabolomics measurements. After the CO:COLLECTION_SUMMARY first passage, subsequent passages were performed in 96-well polystyrene plates CO:COLLECTION_SUMMARY (Greiner Bio-One #655161) filled with 200 μL of growth medium. CO:SAMPLE_TYPE Bacterial cells #TREATMENT TR:TREATMENT_SUMMARY Many combinations of bacterial isolates were assayed. details can be found in TR:TREATMENT_SUMMARY the publicly available preprint here: TR:TREATMENT_SUMMARY https://www.biorxiv.org/content/10.1101/2022.05.30.494065v1.abstract #SAMPLEPREP SP:SAMPLEPREP_SUMMARY Spent media were collected as described above and immediately stored at -80 °C. SP:SAMPLEPREP_SUMMARY Samples were thawed only once, immediately before LC-MS/MS. Thawed samples were SP:SAMPLEPREP_SUMMARY kept on ice, each sample was homogenized by pipetting prior to dispensing. Two SP:SAMPLEPREP_SUMMARY 20-µL aliquots of supernatant were removed from each sample well and dispensed SP:SAMPLEPREP_SUMMARY into two shallow 96-well polypropylene plates, maintained on ice. Additionally, SP:SAMPLEPREP_SUMMARY 5 µL were removed from each sample and combined into a homogenous pool; this SP:SAMPLEPREP_SUMMARY pool was dispensed in 20-µL aliquots and prepared in parallel with samples. SP:SAMPLEPREP_SUMMARY These pooled samples were used for in-run quality control, injected at SP:SAMPLEPREP_SUMMARY predefined intervals over the course of analysis to ensure consistent instrument SP:SAMPLEPREP_SUMMARY performance over time. Samples were analyzed using two complementary SP:SAMPLEPREP_SUMMARY chromatography methods: reversed phase (C18) and hydrophilic interaction SP:SAMPLEPREP_SUMMARY chromatography (HILIC). All samples were analyzed by positive and negative mode SP:SAMPLEPREP_SUMMARY electrospray ionization (ESI+, ESI-). Sample analysis order was randomized to SP:SAMPLEPREP_SUMMARY minimize potential bias in data acquisition. Procedural blanks were prepared by SP:SAMPLEPREP_SUMMARY extracting 20 µL of water in place of bacterial supernatant. Procedural blanks SP:SAMPLEPREP_SUMMARY were inserted throughout the run as additional quality control. #CHROMATOGRAPHY CH:CHROMATOGRAPHY_SUMMARY Bacterial supernatant were analyzed via reversed phase (C18) coupled to a Thermo CH:CHROMATOGRAPHY_SUMMARY Q-Exactive HF high resolution mass spectrometer. Prepared samples were injected CH:CHROMATOGRAPHY_SUMMARY onto an Agilent Zorbax SB-C18 column (100 mm length × 3 mm id; 1.8 μm particle CH:CHROMATOGRAPHY_SUMMARY size) with an additional Phenomenex KrudKatcher pre-column (2 μm depth x CH:CHROMATOGRAPHY_SUMMARY 0.004in ID) maintained at 40°C coupled to an Thermo Vanquish UPLC. The mobile CH:CHROMATOGRAPHY_SUMMARY phases were prepared with 0.1% formic acid in either 100% LC-MS grade water for CH:CHROMATOGRAPHY_SUMMARY mobile phase (A), 100% water or mobile phase (B), 100% acetonitrile. Gradient CH:CHROMATOGRAPHY_SUMMARY elution was performed as follows 3% (B) maintained 0–0.43 min to 97% (B) at 9 CH:CHROMATOGRAPHY_SUMMARY min, maintained until 11 min, returning to initial conditions at 11.5 min and CH:CHROMATOGRAPHY_SUMMARY equilibrating until the end of the run at 14 min. Flow rate is maintained at 0.4 CH:CHROMATOGRAPHY_SUMMARY mL/min. Each sample was analyzed in both positive and negative ionization modes CH:CHROMATOGRAPHY_SUMMARY (ESI+, ESI-) via subsequent injections. Full MS-ddMS2 data was collected, an CH:CHROMATOGRAPHY_SUMMARY inclusion list was used to prioritize MS2 selection of metabolites from our CH:CHROMATOGRAPHY_SUMMARY in-house ‘local’ library, when additional scan bandwidth was available MS2 CH:CHROMATOGRAPHY_SUMMARY was collected in a data-dependent manner.

Metabolomics data was processed using MS-DIAL v4.60 CH:CHROMATOGRAPHY_SUMMARY (https://www.nature.com/articles/s41587-020-0531-2) and queried against a CH:CHROMATOGRAPHY_SUMMARY combination of our in-house MS2 library and MassBank of North America, the CH:CHROMATOGRAPHY_SUMMARY largest freely available spectral repository CH:CHROMATOGRAPHY_SUMMARY (https://doi.org/10.1002/mas.21535).
