“…Regarding wood pulp fibers, the use of TKP to replace starches and galactomannans in papermaking has been described although not widely implemented (Shankaracharya 1998). Motivated by our interest in the use of xyloglucan as a vector to introduce new chemical functionality on cellulose (vide infra), the use of xyloglucan as a wet-end additive has recently been studied in collaboration with Lindströ m and coworkers (Christiernin et al 2003). Isolated tamarind xyloglucan binds to chemical wood pulp fibers with high affinity and improves paper formation and strength properties, the latter of which was independently observed by Buckeridge and collegues (Lima et al 2003).…”

Xyloglucans are the principal polysaccharides coating and crosslinking cellulose microfibrills in the majority of land plants. This review summarizes current knowledge of xyloglucan structures, solution properties, and the mechanism of interaction of xyloglucans with cellulose. This knowledge base forms the platform for new biomimetic methods of cellulose surface modification with applications within the fields of textile manufacture, papermaking, and materials science. Recent advances using the enzyme xyloglucan endo-transglycosylase (XET, EC 2.4.1.207) to introduce varied chemical functionality onto cellulose surfaces are highlighted.

“…Also Bhaduri et al (1995) and Blomstedt et al (2010) reported that pulp and paper properties were very slightly influenced by enzymatic pulp pretreatment. Interestingly, Christiemin et al (2014) found that the addition of xyloglucan to cellulosic pulp improved the strength paper properties. This finding suggests that partial removal of hemicelluloses from pulps leads to worse paper strength properties.…”

Effect of xylanases on refining process and kraft pulp properties

et al. 2017

Results of this study demonstrate that enzymatic pretreatment of pulps enables energy savings in the refining process. Pretreatments of NBSK pulp with 3 different commercial xylanases resulted in a faster increase in the pulp freeness that reduced energy input for refining. The partial xylan removal by these enzymes affected the properties of cellulosic pulp and paper. The tensile properties of paper were improved by pretreatment with a pure xylanase while the additional activity of cellulases in the other two tested enzymes negatively influenced the tear resistance. Only the pure xylanase improved the pulp and paper properties. The results of this study provide evidence that the purity of xylanases used in papermaking is of great importance and may decide of paper quality and production costs.

The effect of barley husk arabinoxylan adsorption on the properties of cellulose fibres

et al. 2008

This study investigates the adsorption of (glucurono)arabinoxylan (GAX) on cellulose fibres and the properties thereof. A water-soluble GAX, from barley husks (Hordeum vulgare), was isolated using chlorite delignification and alkaline extraction followed by enzymatic purification. The isolated GAX fraction showed an arabinose to xylose ratio of 0.22 and a weight average molar mass of 20,200 g/mol, as determined by size exclusion chromatography (SEC) in DMSO:H 2 O. The GAX was adsorbed on cellulose fibres under well controlled conditions, where temperature and initial concentration of GAX proved to be important parameters in controlling the level of adsorption. The adsorption process was also dependent on xylan molecular structure. Carbohydrate analysis on the modified fibres showed a preferential adsorption of low substituted xylans (arabinose to xylose ratio of *0.10). During the adsorption process the GAX solution was analyzed using SEC-RI-MALLS in aqueous solvent, which demonstrated a molecular xylan adsorption on cellulose fibres. Additionally, a decrease in light scattering responses, which corresponds to an adsorption of aggregated xylan and/or xylan with a great tendency towards self-association, could be observed during the adsorption process. This was demonstrated by adsorption of GAX on regenerated cellulose fibres (Lyocell), which compared to native fibres possesses a relatively smooth fibre surface. Atomic force microscopy analysis visualised a heterogeneous decoration of the Lyocell fibres with xylan agglomerates. The effect of GAX adsorption on paper strength was also investigated. A GAX modified kraft pulp showed an evident increase in tensile strength, which might be due to a retained fibre-fibre bonding ability for xylan coated fibrils after drying and rewetting.
