| Abstract: | Background Health-promoting polyunsaturated fatty acids (PUFA) are abundant in forages grazed by ruminants and in vegetable and fish
oils used as dietary supplements, but only a small proportion of PUFA finds its way into meat and milk, because of biohydrogenation
in the rumen. Butyrivibrio fibrisolvens plays a major role in this activity. The aim of this study was to investigate the mechanisms by which PUFA affect the growth
of B. fibrisolvens, how PUFA are metabolized and the metabolic response to growth in the presence of PUFA. |
