Progresses in the research in Lignocellulose Degrading Bacteria and their genes encoding cellulase/hemicellulase in Rumen-A review

Abstract:

Abstract：Rumen of ruminant animals is known as a natural reactor involved in highly efficient lignocellulose degradation. The research on rumen microbes is a subject of keen interest in terms of biofuel development. Traditionally, the studies were dependent on isolating of fibrolytic bacteria, and thereafter the lignocellulose degrading enzymes were analyzed individually. With the development of genomic or metagenomic technologies, a variety of new genes or gene clusters associated with lignocellulose degrading enzymes could be found in rumen, based on which lignocellulose degrading mechanism could be studied and discussed. Previous studies indicate that the lignocellulose degradation process of rumen microorganism is much more complicated, which includes a large number of different rumen microorganisms, enzymes, genes or gene clusters. With the development and maturation of new analysis technologies, much progress on these rumen microbes, enzymes, genes has been made. This review reported the recent progress about these researches.
