C18 unsaturated fatty acid hydrogenation patterns of some rumen bacteria and their ability to hydrolyse exogenous phospholipid.
نویسندگان
چکیده
1. A number of rumen bacteria isolated because of their ability to deacylate phosphatidyl choline, were found, in addition, to hydrogenate polyunsaturated fatty acids. 2. The most active lipolytic organisms had an unusual pattern of hydrogenation of dietary fatty acids in that alpha-linolenic acid was hydrogenated only as far as trans-11, cis-15-octadecadienoic acid.

Role of the protozoan Isotricha prostoma, liquid-, and solid-associated bacteria in rumen biohydrogenation of linoleic acid.
From the simultaneous accumulation of hydrogenation intermediates and the disappearance of Isotricha prostoma after algae supplementation, we suggested a role of this ciliate and/or its associated bacteria in rumen biohydrogenation of unsaturated fatty acids. The experiments described here evaluated the role of I. prostoma and/or its associated endogenous and exogenous bacteria in rumen biohydr...
متن کاملBiosynthesis of Conjugated Linoleic Acid and Its Incorporation into Ruminant’s Products**
Bio-hydrogenation of C18-unsaturated fatty acids released from the hydrolysis of dietary lipids in the rumen, in general, occurs rapidly but the range of hydrogenation is quite large, depending on the degree of unsaturation of fatty acids, the configuration of unsaturated fatty acids, microbial type and the experimental condition. Conjugated linoleic acid (CLA) is incompletely hydrogenated prod...

This study using the rumen simulation technique (RUSITEC) investigated the changes in the ruminal microbiota and anaerobic fermentation in response to the addition of different lipid supplements to a ruminant diet. A basal diet with no oil added was the control, and the treatment diets were supplemented with sunflower oil (2%) only, or sunflower oil (2%) in combination with fish oil (1%) or alg...
متن کاملStimulation of hydrogenation of linoleate in Treponema (Borrelia) sp, strain B2-5 by reduced methyl viologen and by reduced benzyl viologen.
A number of studies have been conducted to elucidate the properties and mechanism of the hydrogenation of Clg unsaturated fatty acids by rumen micro-organisms. Progress in this area has been reviewed by Dawson & Kemp (1970). During screening of a number of pure cultures of rumen bacteria, several species have been shown to hydrogenate linoleate to trans-octadecenoate (Polan, McNeill & Tove, 196...
