Profiling of bacteria by fast atom bombardment mass spectrometry

Positive and negative ion fast atom bombardment mass spectra have been obtained from lysed bacteria introduced without extraction into the mass spectrometer. Phospholipids and other polar lipids are found to be selectively desorbed to provide molecular ions consistent with those observed in spectra...

Zusammenfassung:Positive and negative ion fast atom bombardment mass spectra have been obtained from lysed bacteria introduced without extraction into the mass spectrometer. Phospholipids and other polar lipids are found to be selectively desorbed to provide molecular ions consistent with those observed in spectra of pure lipid samples. Fast atom bombardment mass spectra may serve as an aid in differentiating species.
