M.  aEcological aspects on rumen microbiome.h[electronic resource]  c2017  ap. 367-389  aRuminants are important as suppliers of dairy products for human consumption and are responsible by a large portion of global greenhouse gas emissions. The rumen microbial colonization is a complex process and occurs simultaneously with animal development and maturation of the host immune system. Ruminal microorganisms are responsible for converting energy stored in plant biomass into volatile fatty acid, which are subsequently metabolized and absorbed by the animal. In this chapter, aree brie?y described the rumen compartment and the coevolution between ruminants and microorganisms. Further, are discussed the rumen microbiome composition, including the structure of bacterial and archaeal communities and the role of Protozoa, anaerobic fungi, and bacteriophages in the rumen. Finally, are discussed how the use of molecular tools on rumen microbiome studies has impacted on biotechnological exploitation of this ecosystem.  aMetagenomics  aMicrobial ecology  aRumen microorganisms  aRuminants  aBactéria  aBiotecnologia  aEnzima  aFungo  aRúmen  aAnaerobic microbial communities  aBiomass degrading enzymes  aRumen biotechnology  aRumen microbiome1 aKMIT, M.
