Influence of birch xylan adsorption during kraft cooking and softwood pulp strength.
Xylanase activity was assayed at 50[degrees]C using 1.0% (w/v) birchwood xylan in 50 mM sodium phosphate buffer pH 6.0.
Xylan is the principal hemicelluloses and major plant cell wall polysaccharide component, composed mainly of D-xylose.
Its backbone chain is primarily composed of xylan linkages including a-xylose (~90%) and L-arabinose (~10%) [14].
Xylan is derived from hemicellulose which is one of the three primary components of the plant cell wall [3]and many researchers paid extensive attention to the exploration of xylan because of its abundance and biodegradability.
The NSP including mannans and xylan have cellulose about 12% of the total feed.
