TL;DR: The range of polysaccharide-degrading enzymes formed by three anaerobic rumen fungi (Neocallimastix patriciarum, Piromonas communis, and an unidentified isolate) was monitored following growth on seven mono-, di-, and poly- Saccharide carbohydrate substrates and their modes of action, pH optima, substrate affinities, and response to potential inhibitors were similar.

TL;DR: The rumen fungi Neocallimastix patriciarum, Piromonas communis, and a morphologically distinct but unidentified isolate were cultivated on the polysaccharides starch, cellulose, xylan, and their principal component monosaccharide and disaccharides, and the range and specific activities of the glycoside hydrolases formed were monitored.

TL;DR: Current information on glycolysis and fermentation product generation via cystosolic and hydrogenosomal systems, production of enzymes involved in plant cell wall hydrolysis, lipid metabolism and the role of Chytridiomycetes in ruminal proteolysis is discussed.

TL;DR: Zoospores and vegetative growth phases of three cellulolytic rumen chytridiiomycetes, Piromonas, Sphaeromonas and NF1 have been examined by electron microscopy and compared with published and new data on Neocallimastix.

TL;DR: It is demonstrated that the ruminal bacterial population responds to seasonal changes in feed intake and quality, and it is yet to be determined if these bacterial changes enhance the ability of Svalbard reindeer to survive in the hostile environment of the high Arctic.
