Abstract

The rumen is a complex microbial ecosystem and an active metabolic organ involved in degradation and fermentation of fibrous plant diets. The rumen microbiota is exceedingly diverse and contains representatives of all three domains— Eucarya , methanogenic Archaea, and Bacteria and phages. The digestion is carried out by microbial enzymatic, and mechanical means, i.e., mastication of ingested feed, and churning by rumen muscular movements. Short-chain fatty acids, microbial proteins, CO2, H2, and CH4 are major end products of rumen digestive process.

Highlights
  • Rumen hosts dense population of microorganisms: Eucarya, Archaea, and Bacteria

  • Majority of the rumen microorganisms are obligatory anaerobes and unculturable

  • Rumen is a potentially fertile ground for microbial ecologists, molecular microbiologists from commercial point of view.
