Highlights Regenerated cellulose membranes showed high potential to recover galactoglucomannan (GGM) from spruce sawdust hydrolysate. By the 5 kDa regenerated cellulose membrane, the purity of the GGM increased from 48% to 63%. Filtration by the 10 and 30 kDa membranes facilitated partial separation of xylan from the GGM rich fraction. By the 5 and 10 kDa membranes lignin partially removed

The recovery of hemicelluloses from this process water would both reduce the load on pulp mill water treatment plants and yield a biopolymer suitable as a raw material for renewable products. Extraction of galactoglucomannan from thermomechanical pulp mill process water by microfiltration and ultrafiltration-Influence of microfiltration membrane pore size on ultrafiltration performance.

DOI: 10.1016/j.cherd.2015.12.003. Interaction of galactoglucomannan oligosaccharides with auxin in mung bean primary root. Kollárová K(1), Vatehová Z, Slováková L, Lisková D. Author information: (1)Institute of Chemistry, Slovak Academy of Sciences, Dúbravská cesta 9, 845 38 Bratislava, Slovakia. Karin.Kollarova@savba.sk The main parameters influencing the extraction and hydrolysis of the hemicelluloses, namely, extraction time, temperature, pH, and chip size, were studied. The results show that it is feasible to develop an extraction process for harvesting spruce hemicelluloses, also of large molar masses, for industrial applications by using pressurized hot water extraction.

With hot water extraction at 160°C, 10.5% of wood could be extracted, which corresponds to more than 60% of wood GGM. This article is continuation to the modeling work carried out for hot water extraction and chemical pulp bleaching. The model includes galactoglucomannan, xylan, and cellulose acid–base equilibria, in addition to peeling, stopping, and alkaline hydrolysis reactions of the same carbohydrates, Borrow LU card Computers & networks Copying, scanning & printing Study spaces & reading rooms Lockers and trolleys Order digitizations Find your way around Sweden stands up for open access – cancels agreement with Elsevier LUBcat LIBRIS Galactoglucomannan (GGM) isolated from pine wood chips by hot water extraction was enzymatically hydrolysed into galactoglucomanno-oligosaccharides (GGMOs). Enzymes are known to hydrolyse GGM selectively and depending on the utilized enzyme a different pool of GGMOs can be obtained.
