Diagnostic Fragmentation of Saturated and Unsaturated Fatty Acids by Gas Chromatography–Mass Spectrometry with Pentafluorophenyldimethylsilyl Derivatization
Cellular fatty acids of Peptococcus variables and Peptostreptococcus anaerobius were identified by gas chromatography, mass spectrometry, and associated analytical techniques. Iso- and anteiso-branched-chain acids were major components in both species.
