FIG. 2.

Relative abundance of the total cellular fatty acids of strain Hxd3 grown on pentadecane, perdeuterated pentadecane, hexadecane, and [1,2-¹³C₂]hexadecane. The unlabeled C-even fatty acids are represented by black bars, and the unlabeled C-odd fatty acids are represented by white bars. For cultures grown on perdeuterated pentadecane and [1,2-¹³C₂]hexadecane, only the deuterated (▨) and ¹³C-labeled (▧) fatty acids, respectively, are depicted. All fatty acids shown are identifiable by gas chromatography-mass spectrometry and comprise more than 1% of the total. None of these fatty acids was found in the sterile controls.
