Biohydrogenation 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 کاملInfluence of Carotino oil on in vitro rumen fermentation, metabolism and apparent biohydrogenation of fatty acids.
The study appraised the effects of Carotino oil on in vitro rumen fermentation, gas production, metabolism and apparent biohydrogenation of oleic, linoleic and linolenic acids. Carotino oil was added to a basal diet (50% concentrate and 50% oil palm frond) at the rate of 0, 2, 4, 6 and 8% dry matter of the diet. Rumen inoculum was obtained from three fistulated Boer bucks and incubated with 200...
متن کاملEffects of Heat Processing of Soybeans and Linseed on Ruminal Fatty Acid Biohydrogenation in situ
The aim of this study was to determine and compare in situ biohydrogenation (BH) fatty acids in three forms of soybeans and linseed (raw, extruded and roasted). Nylon bags (5×10 cm) containing 4 g of raw, extruded or roasted soybeans or raw, extruded or roasted linseed were incubated in the rumen of fistulated ewes for 4, 8, 12 and 24 hours. Results for linoleic acid (C18:2) showed tha...
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 کاملRates and efficiencies of reactions of ruminal biohydrogenation of linoleic acid according to pH and polyunsaturated fatty acids concentrations.
Data from a previous study about the effects of pH and of linolenic acid (C18:3n-3) and linoleic acid (C18:2n-6) concentrations on C18:2n-6 biohydrogenation in ruminal cultures were used to calculate the rates and efficiencies of the three reactions of C18:2n-6 biohydrogenation (isomerisation of C18:2n-6 to CLA; reduction of CLA to trans-octadecenoic acids; reduction of trans-octadecenoic acids...
