Microflora of the Rumen

Nature, 1948
QUIN1, in his study of the rumen micro-organisms occurring in sheep fed exclusively on lucerne hay, noted the appearance of large numbers of ovoid, clear cellular organisms with an average size of 8 µ × 4 µ. He showed that rumen fluid rich in these organisms rapidly fermented glucose with the evolution of gas, and that under these conditions the ...

THE HUMAN RUMEN

The Lancet, 1978
The cow is a ruminant, and cow's milk has evolved to promote bacterial growth in the upper small bowel; whereas human milk has evolved to discourage bacterial growth. Examination of the constituents of the two milks shows that their differences can be accounted for in terms of this difference in function.

Lipolysis in the Rumen

Nature, 1958
REISER,1, and more recently Shorland et al. 2, reported experiments in which rumen contents of sheep were incubated in vitro with linseed oil and with oleic, linoleic and linolenic acids. These experiments, and others using the living animal3–5, demonstrated that hydrogenation of double bonds of unsaturated fatty acids occurred and that this was ...

Interspecies cross-feeding orchestrates carbon degradation in the rumen ecosystem

open access: yesNature Microbiology, 2018
Because of their agricultural value, there is a great body of research dedicated to understanding the microorganisms responsible for rumen carbon degradation. However, we lack a holistic view of the microbial food web responsible for carbon processing in

Rumen transfaunation

Immunology Letters, 2014
The aim of this invited mini-review is to summarize the rumen transfaunation literature. Rumen transfaunation using the cud from a healthy donor animal to treat a sick recipient animal was practiced long before our understanding of rumen microorganisms.

Studies on rumen metabolism. VIII. Characteristics of lipases in rumen contents and in rumen bacteria

Journal of the Science of Food and Agriculture, 1974
AbstractSoluble lipases obtained from the rumen contents of pasture‐fed cows had pH optima of 7.0 and 8.0 to 8.5, respectively, with tributyrin and triolein as substrates. At these optima the activity towards tributyrin was about 30 times greater than towards triolein.Tributyrin‐splitting bacteria were abundant in the rumen of pasture‐fed cows but none

The occurrence of bacteriophages in the rumen and their influence on rumen bacterial populations

Experientia, 1974
Se han demostrado que dos cultivos de bacterias de rumen (un baston gram negativo, designado W461, y una cepa de ovalos deEadie) estan infectados con bacteriofagos. El bacteriofago de W461 es templado; aquel de los ovalos es virulento y depleta rapidamente la poblacion bacteriana en vivo.

Comparative Study of the Urease in the Rumen Wall and Rumen Content

Nature, 1966
IN the course of the ruminohepatic nitrogen cycle1,2, or by supplementation in feeding3, a considerable amount of urea can enter the rumen. The ureolytic activity of the rumen content was investigated and found to be due to some species of ruminal micro-organisms.

Rumen function.

2005
This chapter deals with the effects of dietary changes on the fermentation processes in the rumen and their consequences for the amount and type of nutrients delivered to the ruminant host, as well as the mathematical description of these processes. In addition to the fermentation in the lumen, the tissues in the rumen wall are also of importance for ...
