Hidrólisis enzimática de materiales lignocelulósicos

Resumo

Biorefineries development as production model kindred to the traditional refineries has been favoured by the different environmental policies adopted by different national and supranational organisms, and also by the scarcity of the fossil fuels and no-renewable raw materials. Nowadays, biorrefineries can be defined as every production process based on biomass, obtaining as result final or intermediate chemical products and/or energy, food and feed, and employing environmental sustainable production processes.There are many types of biorefineries, and they can be classified according to the process that are employing, what kind of products are producing and in terms of the biomass used as raw material. Among all the different biorefineries, nowadays is gaining importance those that are using lignocellulosic biomass to obtain products and energy. Lignocellulosic biomass is composed by, mainly, cellulose, hemicellulose and lignin. All of these biopolymers can be processed and separated into their fundamental components, which can be used as reactive or intermediate products in many different industrial processes...
