Some rumen bacteria degrading fructan

Letters in Applied Microbiology, 1992
Degradation of fructan obtained from timothy (Phleum pratense L.) by the following six species of bacteria isolated from sheep rumen was studied: Streptococcus bovis, Bacteroides ruminicola, Selenomonas ruminantium, Butyrivibrio fibrisolvens, Treponema bryantii and Treponema saccharophilum.

Aspects of lignin degradation by rumen microorganisms

Journal of Biotechnology, 1993
Abstract The paper discusses the problems presented by lignin to animal production, particularly in countries with hot climates, where the degree of lignification in plants is extremely variable causing unpredictable reductions in digestibility. The difficulty of chemically defining lignin compounds is reviewed with the conclusion that a combination ...

Identification of rumen bacteria that anaerobically degrade nitrite

Canadian Journal of Microbiology, 1988
Fifty-one pure strains of rumen bacteria, representing 15 genera, were tested for their ability to metabolize nitrite. Twenty-five of the strains, belonging to eight genera, were capable of growth and nitrite metabolism in nitrite-containing medium sterilized by autoclaving.

Do Naïve Ruminants Degrade Alkaloids in the Rumen?

Journal of Chemical Ecology, 2005
Three different methods for the culture of rumen microorganisms (Hungate's technique, the Hohenheim in vitro gas production method, and the semicontinuous rumen simulation technique) were employed to study the influence of various alkaloids (sparteine, lupanine, cytisine, atropine, quinidine, lobeline, harmaline, arecoline, nicotine, caffeine ...

Polysaccharide degradation by rumen microorganisms

1997
Polysaccharides entering the rumen can be considered as belonging to one of two general types: plant storage polysaccharides such as starch and the fructosans, or the structural polysaccharides which compose the greater part of all plant cell walls and which are loosely considered to form the fibrous component of animal feedstuffs.

Hemicellulose‐degrading Enzymes Synthesized by Rumen Bacteria

Journal of Applied Bacteriology, 1981
Over 100 bacterial cultures isolated from ovine rumen contents by enrichment techniques in polysaccharide‐containing media were examined for the ability to degrade plant cell wall structural polysaccharides. Approximately two‐thirds of the isolates retained were Gram negative and amongst the coccoid isolates diplococci predominated.

Hemicellulose-degrading enzymes in rumen ciliate protozoa

Current Microbiology, 1985
Hemicellulose-degrading enzymes were detected in cell-free extracts of protozoa representing ten genera of rumen entodiniomorphid and holotrich ciliates. The enzyme preparations released monosaccharides, disaccharides, and oligomers fromLolium perenne hemicellulose B and oat spelt xylan; the activity was present both in cells isolated directly from ...

Studies on Lignocellulose Degradation by Rumen Microorganism

Advanced Materials Research, 2013
Lignocellulosic material is the earth's most abundant renewable resource, but because of its stable and complex structure, it is not easy for depredating and utilizing for a long time. Rumen can degrade lignocellulose, and is one of nature's most efficient fermentation fermenter; to be study rumen microorganisms has the potential to provide valuable ...

Anaerobic degradation of dehydrodiisoeugenol by rumen bacteria

Journal of Fermentation Technology, 1987
Abstract The degradation of dehydrodiisoeugenol (DDIE) by cow rumen bacteria was studied under strictly anaerobic conditions. After two days of cultivation, about 23% of DDIE (1.2 mM) was degraded to volatile fatty acids (VFA) such as acetic acid, propionic acid and butyric acid.
