Abstract
The biohydrogenation products [microbial metabolites] 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 100mg/100ml of rumen liquor, monoenoic acids, including cis-octadec-15-enoic acid, were the major products.
