متن کاملBiohydrogenation of Unsaturated Fatty Acids by Rumen Bacteria.
Polan, C. E. (North Carolina State of the University of North Carolina, Raleigh), J. J. McNeill, and S. B. Tove. Biohydrogenation of unsaturated fatty acids by rumen bacteria. J. Bacteriol. 88:1056-1064. 1964.-A simple, rapid, specific assay for the biohydrogenation of unsaturated fatty acids was developed. With this assay, it was shown that washed suspensions of mixed rumen bacteria hydrogenat...
متن کاملEffects of pH and concentrations of linoleic and linolenic acids on extent and intermediates of ruminal biohydrogenation in vitro.
Three experiments were conducted by in vitro incubations in ruminal fluid to investigate the effects of pH and amounts of linoleic and linolenic acids on the extent of their biohydrogenation, the proportions of conjugated linoleic acid (CLA) and trans-C18:1 as intermediates, and the ratio trans-10:trans-11 intermediates. The effects of pH and amount of linoleic acid were investigated in kinetic...
متن کاملThe biohydrogenation of alpha-linolenic acid and oleic acid by rumen micro-organisms.
1. alpha-[U-(14)C]Linolenic acid was incubated with the rumen contents of sheep and the metabolic products were characterized by thin-layer chromatography, gas-liquid chromatography and absorption spectroscopy in the ultraviolet and infrared. 2. A tentative scheme for the biohydrogenation route to stearic acid is presented. The main pathway is through diconjugated cis-cis-cis-octadecatrienoic a...
متن کاملA Review on Biohydrogenation and Effects of Tannin on It
The process called biohydrogenation occurs mainly in ruminant animals and during it, unsaturated fatty acids, and particularly poly-unsaturated ones (linoleic and linolenic) coverts to a saturated form of stearic acid. For many years, the beneficial effects of biohydrogenation intermediate fatty acids like cis-9 trans-11 linoleic acid, the main natural isomer of conjugated linoleic acids (CLA),...
