Abstract: The rumen is a fermentative chamber that is the place to a variety of microorganisms, including bacteria, fungi, protozoa, archaea, bacteriophage and Oscillospira. The rumen fungi are obligate anaerobes, zoospore producers, and extremely molecular oxygen sensitive. Rumen fungi is one of the rumen microorganisms that can break down fibre because it produces extremely potent lignocellulose-degrading enzymes. The number of flagella in zoospores, thallus morphology and rhizoid type are used for classifying rumen fungi into several genera. Fungi can produce rhizoid, which can penetrate feed particles and physically and chemically leads to breakdown of plant cell walls thus, the presence of rumen fungi is crucial. The degradability of feed particles is also increased by the production of fiber-degrading enzymes by rumen fungi, including cellulase, hemicellulase and pectinase. So, this review paper aims to discuss the potential of rumen anaerobic fungi for improving fiber digestibility in livestock.
