WebThe biohydrogenation theory proposes that under certain dietary conditions, typical pathways of rumen biohydrogenation are altered to produce unique fatty acid intermediates that inhibit milk fat synthesis. Trans-10, cis-12 conjugated linoleic acid (CLA) has been identified as one example that is correlated with the reduction in milk fat. WebRumen ciliate protozoa do not carry out biohydrogenation, yet protozoal lipids are much more highly enriched in CLA than bacterial lipids. How could this happen if protozoa do not metabolise PUFA? The answer seems to lie in the ingestion of plant organelles, particularly chloroplasts, and the partial metabolism of the fatty acids by ...

WebTherefore, compared with bacterial biohydrogenation, the overall impact of fungal biohydrogenation processes in the rumen is probably modest in light of not only the lower reaction rates but also lower fungal population numbers in this ecosystem (Jenkins et al., 2008; Nam and Garnsworthy, 2007). 2.3 Conjugated Linoleic Acid Production in the Rumen Weblinolenic acid biohydrogenation to stearic acid are shown in Figure 3 (Ferlay et al., 2024).
