The occurrence of cis-octadec-15-enoic acid as a major biohydrogenation product from methyl linolenate in bovine rumen liquor

The biohydrogenation products from methyl linolenate varied according to its concentration in the rumen. At low concentrations, over 60% of the biohydrogenated products was stearic acid, but when the concentration was raised above 100 mg/100 ml of rumen liquor, monoenoic acids, including cis-octadec-15-enoic acid, were the major products.
