GNPS - Ecoli_strains_extracellular_metabolome_comparisons_Study1

Data from a comparative metabolomics study of extracellular metabolomes of 10 E coli strains of phylogroup B2 (5 strains; UPEC 536, APEC O1, CFT073, J96, Nissle 1917) and other phylogroups (5 strains; 042, MG1655, HS, O103:H2, TUV93-0). pHILIC-MS full scan data of all supernatant extracts (three replicates - 1:3:1 H20-methanol-chloroform extractions) was obtained in alternating ionization mode: MzXML files with positive ionization mode spectra and negative ionization mode spectra are provided. Controls (blanks, solvent and medium controls, and pooled samples run across the batch, are included as well). pHILIC-MS/MS data of selected supernatant as well as whole cell extract samples was obtained for metabolite annotation purposes. The resulting MzXML files in positive ionization mode and negative ionization mode are provided.
