Kinetics of alkaline delignification of black spruce wood [PDF]
, 1982 A previously proposed kinetics equation describing the delignification of wood in soda-anthraquinone (AQ) liquors was shown to be valid under isothermal conditions, and was extended to describe variation in initial alkali charge.

Effect of refining on delignification with a lacasse/xylanase treatment [PDF]
BioResources, 2012 Previous research has demonstrated that a laccase/xylanase system (LXS) from white-rot fungus (Lentinus lepideus) has the same ability to delignify as a laccase/mediator system (LMS).

Influence of xylan content on the oxygen delignification performance of eucalypt kraft pulps as studied using prehydrolysis and xylanase treatments [PDF]
BioResources, 2012 Common metrics for evaluating the efficiency of oxygen delignification include the kappa number and Klason lignin content. As a change in xylan content often leads to a change in HexA content, the kappa number must be corrected for the HexA contribution ...

Enzyme loading dependence of cellulose hydrolysis of sugarcane bagasse
Química Nova, 2012 The enzymatic hydrolysis of steam-pretreated sugarcane bagasse, either delignified or non-delignified, was studied as a function of enzyme loading. Hydrolysis experiments were carried out using five enzyme loadings (2.5 to 20 FPU/g cellulose) and the ...
