FIG. 6.
Comparison of fatty acid profiles of Rhodococcus sp. strain Q15 cells grown on glucose-acetate, hexadecane, or diesel fuel at 5 or 24°C. Unk, unknown, putative fatty acid; c, cis, t, trans; cyc, cylcopropane; Me, methyl. The values are means based on triplicate samples (standard deviation, <10% of mean). Unknown fatty acids 3 and 4, which were present in relatively large quantities in cells grown on hexadecane at 5°C, were tentatively identified by gas chromatography-mass spectrometry as C16:1 and methyl-C15:0, respectively.
