Production of film using polysaccharides from lignocellulosic biomass


The xylan, main hemicellulose of grasses, appears in the focus of many studies due to its potential in technological applications. Other products of industrial interest are holocellulose and a-cellulose, which can be produced from lignocellulosic biomasses. Associated with xylan, these macromolecules will be evaluated in the formation of new matrices for the preparation of biodegradable materials (films). The xylan can influence the characteristics of the film (mechanical and thermal resistance) depending on its chemical composition, pending groups and degree of polymerization (GP). In this context, the present proposal aims to advance the applications of xylan, as in the production of xylo-oligosaccharides and the use of xylan in the formation of films. Also, important is the production of enzymes with action on xylan chain, modifying their structure (GP and pending groups). For film formation it may be important to develop an enzymatic extract able to break bonds between xylan chain and pending groups, generating a free xylan of pending groups; or cleave different bonds in the main chain generating xylan with different degrees of polymerization. Thus, this study will develop enzymatic extracts for xylan chain modification and production of polysaccharides for making films and biodegradable materials (associated with starch, ±-cellulose and holocellulose). The preparation of biodegradable material using vegetable biomass carbohydrates is a product of industrial interest, with immediate need in the market, and also contributing to sustainable environmental development.
