Fig. 2.

Partial chromatogram with peaks representing fatty acids from 22:0 to 22:6n-3. These chromatograms obtained from (a) 0, 8, 12 and 24 h incubations with 22:6n-3 (20 μg/mL) and (b) 48 h incubations with 22:6n-3 (20, 40 and 80 μg/mL). In both cases Butyrivibrio proteoclasticus P18 had grown in the media containing 50 % (v/v) autoclaved- uncentrifuged rumen fluid. Peaks visible at 0 h represent the fatty acids present in the rumen fluid and peaks numbers (1–12) represent new peaks formed during the 22:6n-3 metabolism
