Oleate Hydratase in Lactobacillus delbrueckii subsp. bulgaricus LBP UFSC 2230 Catalyzes the Reversible Conversion between Linoleic Acid and Ricinoleic Acid

Microbiology Spectrum, 2021
Conjugated linoleic acid (CLA) has been the subject of numerous studies in recent decades because of its associated health benefits. CLA is an intermediate product of the biohydrogenation pathway of linoleic acid (LA) in bacteria.

Effect of selected plant species within biodiverse pasture on in vitro fatty acid biohydrogenation and tissue fatty acid composition of lamb

Animal, 2018
The effect of botanical diversity on supply of polyunsaturated fatty acids (PUFA) to ruminants in vitro, and the fatty acid (FA) composition of muscle in lambs was investigated.

Isomers of conjugated linoleic acids are synthesized via different mechanisms in ruminal digesta and bacteria

Journal of Lipid Research, 2007
Digesta samples from the ovine rumen and pure ruminal bacteria were incubated with linoleic acid (LA) in deuterium oxide-containing buffer to investigate the mechanisms of the formation of conjugated linoleic acids (CLAs).

Cysteamine-supplemented diet for cashmere goats: A potential strategy to inhibit rumen biohydrogenation and enhance plasma antioxidant capacity

Frontiers in Veterinary Science, 2022
Cysteamine (CS), as a feed supplement, can increase the level of growth hormone (GH) in the blood, promote animal growth. However, little attention has been paid to the effects of CS on the rumen microbiome and metabolic profile in cashmere goats.

Gut microbiology – broad genetic diversity, yet specific metabolic niches

Animal, 2008
Analysis of 16S ribosomal RNA (rRNA)-encoding gene sequences from gut microbial ecosystems reveals bewildering genetic diversity. Some metabolic functions, such as glucose utilisation, are fairly widespread throughout the genetic spectrum.

A Review of Rumen Biohydrogenation and Efficient, Green Production of High-Quality Ruminant Products: Mechanisms, Opportunities and Challenges

Animals
Rumen biohydrogenation is a microbial process that converts dietary unsaturated fatty acids into more saturated products and produces a range of intermediates that can affect animal products and rumen fermentation.

Dietary Supplementation of Olive Pomace in Lactating Buffaloes: Effects on Milk and Yogurt Composition and Fatty Acid Profile

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Olive pomace in lactating buffaloes: Fifteen lactating buffaloes were fed with 0%, 7.5%, and 15% olive pomace substituted with wheat flour for 45 days. Replacing olive pomace with wheat flour in the diet of lactating buffaloes increased milk fat, the concentration of short‐chain and unsaturated fatty acids, and conjugated fatty acids.

Nutritional Level and Type of Feed on the Reproductive Performance of Ewe and Its Effects on Offspring

Reproduction in Domestic Animals, Volume 61, Issue 8, August 2026.
ABSTRACT The amount and source of nutrition are important factors that influence an ewe's reproductive ability, but the effects of diet on the reproductive performance of its offspring are unclear. This study aimed to investigate the impact of maternal nutrition (level of nutrition and source) on the reproductive performance of ewes and their female ...

Changes in Rumen Microbial Profiles and Subcutaneous Fat Composition When Feeding Extruded Flaxseed Mixed With or Before Hay

Frontiers in Microbiology, 2018
Extruded flaxseed (25%) and ground hay (75%) were each fed (DM basis) either together in a total mixed ration (TMR) or as flaxseed first followed by hay (non-TMR) to three pens of eight crossbred steers (n = 24 per diet) for 240 days.

Fats, Fire and Bronze Age Funerary Rites: Organic Residue Analysis of Wide Horizontal Rim Vessels From Burial Contexts in Northwest Portugal

Archaeometry, Volume 68, Issue 3, Page 298-310, June 2026.
ABSTRACT This study presents the first GC‐MS–based analyses of wide horizontal rim vessels with well‐defined funerary contexts, from Middle Bronze Age Portugal (Quinta do Amorim 2 and Pego). Organic residues from two vessels revealed ruminant fats and plant oils, alongside molecular markers of heat exposure.
