Fig 6. Relative proportions of specific branched-chain fatty acids (FAs) out of total FAs found in L. monocytogenes cells harvested across five growth phases at 4°C and 20°C.

A) anteiso C15:0, B) iso C15:0, and C) anteiso C17:0. Lipids were extracted from cell concentrates and resulting fatty acid methyl esters (FAME) were analyzed by gas chromatography. See Fig 1 for information about growth phases.
