FIG. 2.

Relative abundance of the total cellular fatty acids of strain AK-01 grown on tetradecane (a), pentadecane (b), hexadecane (c), and heptadecane (d). Only those which can be identified and comprise more than 1% of the total are shown. C-even fatty acids are represented by black bars, and C-odd fatty acids are represented by white bars. The 2-methyl, 4-methyl, and 6-methyl fatty acids are denoted by the numbers 2, 4, and 6, respectively. (The 2-Me-17:0 fatty acid is also shown, though it constitutes only 0.7% of the total.) No fatty acid was observed in the sterile controls.
