Recent Advances in Cellulosome and Cellulosome-like Complex of Cellulolytic Bacteria in the Rumen

Roughage can be degraded efficiently by rumen microbes,while rumen bacteria especially cellulolytic bacteria play the important role in degradation of fibrous materials.It has been demonstrated that only the bacteria adhered to feed particles are directly responsible for cellulose degradation.The bacterial adhesion to feed is prerequisite to cellulose degradation.The cellulosome is a large complex of multienzymes produced by anaerobic bacteria and fungi for the efficient degradation of plant cell-wall polysaccharides.The molecular structures of cellulosome and advances in cellulosome and cellulosome-like complex of predominate cellulolytic bacteria in the rumen as well as evidence for the occurrence of these structures in the rumen bacterial species were reviewed.
