The raising of the use of fuels, the oil's finite supply and concerns about global warming make it clear that the search for new fuels is important. One answer for this problem is the use of lignocellulosic biomass (agricultural waste, for example) - which make up about 75% of dry weight of plant cell walls. This process uses enzymatic hydrolysis, which is one of the most complex and expensive steps nowadays. While the saccharification of lignocellulose remains a problem for industry, it is carried out effectively in the natural environment by microbial communities. Because less than 1% of the microorganisms can grow in pure cultures, the cellulose hydrolysis have been studied in a few well characterized organisms. Thus, the discovery and study of new enzymes and proteins associated with the lignocellulose degradation is necessary for the development of a efficient and cost-effective process. This can be achieved by the use of an integrated proteomics and metatranscriptomics approach. Therefore, the objectives of this work are discover new enzymes related with lignocellulose hydrolysis, select the most promising ones and characterize their biochemistry and three-dimensional structure.
