Abstract
Direct injection mass spectrometry was amended with chromatographic methods in analysis of membrane phospholipids of Bacillus subtilis mutant strain which contains four polar headgroups only phosphatidylglycerol phosphatidylethanolamine phosphatidylserine and phosphatidic acid Phospholipid classes were determined by thin layer chromatography as the basic method Analysis of fatty acids by gas chromatography determined relative abundances of saturated unsaturated linear and branched C14 to C18 fatty acids in phospholipids Experimental data measured by direct injection mass spectrometry in the m/z range of 590–790 were used to estimate theoretical phospholipid composition which was compared with the data of chromatographic methods The phospholipid class relative abundances measured by mass spectrometry did not agree fully with those of thin layer chromatography and the probable explanation was proposed The direct injection mass spectrometry approach seems to be fast and easy procedure suitable for analyses of proportional changes in phospholipid composition and can be used as a complementary method for trend analyses and in process monitoringThe work was performed at the Institute of Chemistry of the Faculty of Natural Science of Comenius University with support from SVV260317and Mobility Fund of Charles University in Prague further support was provided by project 1318051P from the Czech Science Foundation and Grants APVV084011 APVV041610 APVV006111 and APVV028612 from Slovak Research and Development Agency
