1. Production and engineering of a xyloglucan endo-transglycosylase from Populus tremula x tremuloides
Abstract : The aim of this work was to develop a production process for the enzyme xyloglucan endo-transglycosylase from Populus tremula x tremuloides (PttXET16-34). The natural transglycosylating activity of this enzyme has previously been employed in a XET-Technology. READ MORE

2. Coagulation of Cellulose: from Ionic-Liquid Solution to Cellulose Nanostructure
Abstract : Abstract A linear chain of glucose monomers, cellulose, provides the structural reinforcement of the cell walls of plants and constitutes almost half of their dry mass. Wood and other plant-based raw materials are processed on a large industrial scale to isolate the cellulose, which is then dissolved. READ MORE

3. Novel uses of bio-polymers in composites : from chemistry to processing of materials and food
Abstract : Plant bio-polymers obtained as industrial side-streams (wheat gluten and potato proteins) and specifically designed potato starch and hemp fibres were used to produce composite materials. Fractionated pea protein and pea dietary fibres were used to make pasta-like sheets for production of healthy food. READ MORE

4. Bio-based materials from crambe and carinata industrial oilseed meals : compression moulded and extruded oilseed meal plastics
Abstract : Protein-based plastics are considered as a new route for valorisation of oilseed meal from the industrial oil crops Crambe abyssinia (crambe) and Brassica carinata (carinata) as they cannot be used for animal feed or human food. To convert oilseed meals into protein-based plastic films compression moulding was used with varying processing temperature, chemical additives and protein extraction conditions. READ MORE

5. Processing and characterization of membranes based on cellulose nanocrystals for water purification : Nanocellulose as functional entity
Abstract : Membrane technology is being extensively used in water purification as an energy efficient and low cost process. Nanostructured (NSM) and nanoenabled (NEM) membranes are favored in this context as nanoscaled entities are expected to provide high surface area, high mechanical properties and versatile surface chemistry as well as provide better control on the pore size and distribution, flux and selectivity of the membrane.
