FunEnzFibres will explore novel mechano-enzymatic modifications on cellulose and cellulosic fibres using LPMOs and selected hydrolases for development of high-value products in the forest industry.
Increased use of renewable materials will be one of key issues in future bioeconomy. Well-performing, reasonably priced and sustainable raw materials are needed for the industry to succeed in this development. Cellulose, being the most abundant biopolymer on earth is an interesting raw material for many applications. Cellulose could be the super material of the future, replacing fossil-based materials in textiles, packaging and plastics, and create additional value in the forestry. However, for this potential to be realized, new approaches and tools to modify cellulose are needed.
Wood cellulose is currently used primarily for preparation of paper, paperboard and packaging. To increase a profit while maintaining the market balance, the forest industry will need to reorient towards higher value products e.g. textiles, hygiene and adsorbent products, composites, conductive materials, flexible circuits, printable electronics, and more. Simultaneously, the processing and refining methods must become more energy efficient and environmentally friendly. Recent development in enzyme technologies provide new possibilities.
Today, a new set of enzymes are ready to be explored. Lytic Polysaccharide Monooxygenases (LPMOs) are a novel versatile type of carbohydrate-modifying enzymes, which were discovered in 2010 (Vaaje-Kolstad et al., 2010). Most of application-oriented research on LPMOs has focused on lignocellulose saccharification, in which LPMOs greatly enhance hydrolytic efficiency in synergy with hydrolases.
In contrast, LPMO research on fibre modification has just begun. LPMOs are active on both amorphous and crystalline regions of celluloses, and importantly, introduces new functional groups at the cleavage site through an oxidative mechanism. These new functional groups can be expected to modify surface structure and integrity of pulp fibres, alter water binding properties and charge, and allow for fibre functionalization through site specific chemical modifications.
We aim to study LPMO induced modification on cellulosic materials in the present state-of-the-art project. We will examine the possibilities of LPMOs to open, rearrange and modify structurally different celluloses in combination with existing knowledge in enzymatic fibre refining, and investigate functionalization of cellulosic fibres with new reactive chemical groups. Based on these studies, we will propose industrial applications in close collaboration with the project industrial partners; Borregaard, MetsäFibre, UPM-Kymmene Corporation, Essity GHC R&D Tissue, Acticell GmbH, and Novozymes.
