High Resolution Magic Angle Spinning (HRMAS) NMR spectroscopy was applied to determine the metabolite profile of live Pseudomonas aeruginosa bacteria. One-dimensional and 2-dimensional HRMAS NMR was performed on intact bacterial cells represents a promising method that could provide in vivo information of metabolomics in live bacteria. This in vivo NMR biomedical technique may prove to be a helpful tool in gene function validation, the study of pathogenesis mechanisms, the classification of microbial strains into functional/clinical groups and the testing of anti-bacterial agents and to distinguish the metabolic profile of different mutants.
