Cellulolysis uses hydrolosis on pretreated lignocellulosic materials, enzymes break down complex cellulose into simple sugars like glucose. Gasification converts 

A lot of research interest is focused on understanding the lignocellulose structures. Lignin, among the three major wood components, represents most difficulty for microbial degradation because of its complex structure and because cross‐linking to hemicellulose makes wood such a compact structure. Lignocellulose has evolved to resist degradation and to confer hydrolytic stability and structural robustness to the cell walls of the plants. This robustness or "recalcitrance" is attributable to the crosslinking between the polysaccharides (cellulose and hemicellulose) and the lignin via ester and ether linkages. Rumen can degrade lignocellulose, and is one of nature's most efficient fermentation fermenter; to be study rumen microorganisms has the potential to provide valuable solutions to renewable energy, processing of agricultural waste, organic waste etc. Research methods vary from screening of cellulose-degradation bacteria, enzymatic characterization, to the use of metagenomics technology to get Lignocellulose degradation in Cerambycids and other common wood-feeding insects Lignin limits the accessibility of cellulose for degradation by digestive enzymes.

Many Cerambycids, have the ability to produce endoglucanases and glycoside hydrolases to disrupt random β-1,4 linkages in cellulose chains and hydrolyze β-1,4 linkages in cellobiose disaccharides. Understanding lignocellulosedegradation under natural conditions forms thebasis of any lignocellulose-based application.A variety of microorganisms and mechanisms areinvolved in the complete biodegradation oflignocellulose in natural environments rangingfrom soil and rumen ecosystems to the termitehindgut. lignocellulose degradation under natural conditions forms the basis of any lignocellulose-based application. Delignification, or lignin-modification, facilitates the decomposition of lignocellulose in woody plant biomass.

The biochemistry of lignin degradation by actinomycetes remains poorly understood and the enzymes involved have yet to be identified. There is more information on the enzymology of cellulose and hemicellulose degradation, but how these different groups of enzymes and their component proteins interact to solubilise lignocellulose is largely unknown.
