Molecular Basis of the Interactions and Recalcitrance of Lignocellulosic Biomass

Lignocellulosic biomass represents the main renewable resource from the biosphere for the production of biofuels, platform chemicals and bio-based materials. Lignocellulose consists of a complex polymeric network of cellulose microfibrils embedded in a matrix of hemicelluloses, pectins, and lignins with exquisite organization from the nano- to the microscale. However, the heterogeneity of the lignocellulose polymeric …

FibreFuse – Biobaserade kolfiber: Hur undviks att biobaserade kolfibrer fastnar i varandra under tillverkningen?

Att använda kolfibrer som armering i kompositer ger ett lättviktsmaterial som kan ersätta stål, aluminium eller glasfiber i många konstruktioner, t.ex. i fordonsindustrin eller till turbinbladen i vindkraftverk. Dessvärre är dagens kommersiella kolfibrer för dyra för många tillämpningar och även tillverkade av fossilbaserade polymerer. Lignin har länge ansetts vara en speciellt attraktiv kandidat som råmaterial …

Ex situ and in situ advanced electron microscopy of enzymatic action for biomass tailoring and transport paths in conducting fibres and yarns

The structure of wood is complex with many components. As new cellulose-based materials and devices are to be developed and optimized it is crucial to understand the material microstructure of wood and also the properties of its individual microstructural constituents. Electron microscopy offers a unique capability for site specific imaging, diffraction and spectroscopy with high  …

Polysaccharide Monooxygenases (LPMOs) for Advanced Nanocellulose Materials

LPMOs (lytic polysaccharide monooxygenases) are oxidative enzymes that enhance cellulose fibrillation by introducing charged carboxyl groups onto the cellulose surfaces in aqueous reaction conditions. The use of LPMOs in production of nanocelluloses could reduce the need of hazardous chemicals and facilitate more environmentally friendly processes. The aim of this subproject is to produce recombinant LPMOs …
