Abstract. Hot-water extraction of hemicelluloses, especially galactoglucomannans, from fractions of ground spruce wood with different particle sizes was studied at 170°C with extraction times up to 60 min. Extraction of spruce sapwood, heartwood, and thermomechanical pulp (TMP) was also compared at 160 to 180°C.

Another model dealing with kraft pulping is model by Bogren et al.23 The model includes time-dependent rate constant and mathematical pre-exponent that are dependent on the degree of delignification and temperature. ASPAG : Invasive aspergillosis (IA) is a severe infection that occurs in patients with prolonged neutropenia, following transplantation or in conjunction with aggressive immunosuppressive regimens (eg, prolonged corticosteroid usage, chemotherapy). 1973-11-01 · A galactoglucomannan has been isolated by fractionation of the alkali-soluble hemicelluloses of the leaf and stem tissues of red clover (Trifolium pratense L.). The hemicellulose contains galactose, glucose, and mannose residues in the molar ratios 0.25:1.0:1.1 and accounts for ca . 25% of the mannose residues present in the clover tissues. 2005-03-01 · A galactoglucomannan (GGM), isolated from the lichen Cladonia ibitipocae, consisted of a (1 → 6)-linked main chain of α-mannopyranose units, substituted by α- and β-d-galacto (α- and β-d-Galp)-, β-d-gluco (β-d-Glcp) - and α-d-mannopyranosyl (α-d-Manp) groups, and was sulfated giving a sulfated polysaccharide (GGM-SO 4) with 42.2% sulfate corresponding to a degree of substitution of 1.29.
