The INCT-Bioethanol has made significant progress in studies of the composition of the sugarcane cell wall in recent years, providing important information on the structure of polymers and how enzymes access the wall during hydrolysis, aiming to increase cellulose conversion and hemicellulose into monosaccharides. The present proposal aims to integrate this knowledge to develop enzymatic …
During the second phase of the INCT-bioethanol we intend to integrate the knowledge obtained during the last 6 years to assemble enzyme consortia that will hydrolyze the cell walls of sugarcane quickly and efficiently. The main focus will be to design enzyme consortiums that can be used to hydrolyze diverse sugarcane biomasses as well as genetically and chemically transformed varieties. T…
Brazil is the country with the highest biodiversity in the world. The microbiota present in different Brazilian biomes remains almost unknown and minimally studied, representing great potential for discovery, application in scientific research and industrial activities. Considering Brazil's great biodiversity, in 2010 the National Biodiversity Research System (SISBIOTA-Brazil) started iso…
Lipases (EC 3.1.1.3) comprise a biotechnologically important group of enzymes because they are able to catalyze both hydrolysis and synthesis reactions, depending on the amount of water in the system. One of the most interesting application of lipase is in the biofuel industry for biodiesel production by oil and ethanol (or methanol) transesterification. Entomopathogenic fungi, which are …
The immobilized lipases provide certain advantages of exploitation in relation to the soluble enzymes, making them more desirable for certain applications, because they provide greater thermal and pH stability, keeping them stable throughout the processo The improvement of the catalytic properties through the use of immobilization techniques, so that making them more stable and less expen…

Lignocellulosic biomass is an abundant resource composed mainly of cellulose, hemicellulose and lignin polymers. These polymers are a renewable energy source for the production of biofuels and other compounds with high added value. However, its components are not readily available for bioconversion, and a set of enzymes is required its to deconstruct. Enzymatic application is still limite…
Modern society is searching for ways to develop more sustainable processes that reduce carbon emissions, promote proper waste reuse, decrease dependence on oil, and use lignocellulosic biomass as a raw material to produce fuels, chemicals, energy, and materials. The objective of this project is to develop an efficient degradation system for lignocellulosic biomass using enzymatic cocktail…
Mushrooms belonging to the Basidiomycota phylum produce an arsenal of enzymes responsible for degrading organic matter and other synthetic molecules. Some of the enzymes with the highest catalytic efficiency and, therefore, greater interest from researchers' point of view in the biotechnology sector are laccases. These phenol oxidases catalyze the oxidation reaction of aromatic or phenoli…
During the hydrolysis process of the biomass one of the critical points is the rapid degradation of the enzymes. Therefore, techniques to stabilize and reduce inactivation of enzymes, due to the distortion of their native structure by the influence of temperature, pH and organic solvents, are quite attractive. Immobilization of enzymes has been employed for this purpose, making the proces…

Enzyme immobilization has been widely used as a strategy to reduce the costs of enzymatic processes. This strategy facilitates catalyst recovery, increases stability under adverse conditions and facilitates the reuse of enzymes. The development of protocols for immobilization and stabilization of industrial enzymes is a very interesting goal in enzyme biotechnology, since immobilized and …
The xyloglucan (XG) is the predominant hemicellulose at the primary cell wall of thesuperior plants. This includes all the dicotyledonous and non-gramineous monocotyledonous plants. It is usually found strongly associated to the cellulose through hydrogen bonds, forming a tridimensional network of cellulose and xyloglucan. It is probably the second most abundantpolymer in nature, after ce…
The depletion of fossil fuels and the pollution generated by them, such as the emission of greenhouse gases, has stimulated the search for alternative and renewable sources of energy. Biomass produced by fast-growing grasses such as Panicum genus, commonly used as fodder, can be important sources of clean energy production, but it is necessary to estimate their biomass potential productio…
