TLDR
In this article, xylanase pretreatment was used to improve pulpability of wheat straw and produce pulps with lower kappa number, lower rejects and similar yields of screened-pulps under identical pulping conditions.About:

Xylanases from fungi: properties and industrial applications
Maria de Lourdes Teixeira de Moraes Polizeli,A C S Rizzatti,Rubens Monti,H. F. Terenzi,João Atílio Jorge,Dalton de Souza Amorim +5 more
TL;DR: There has been much industrial interest in xylan and its hydrolytic enzymatic complex, as a supplement in animal feed, for the manufacture of bread, food and drinks, textiles, bleaching of cellulose pulp, ethanol and xylitol production.

Ferulic and p-coumaric acids extraction by alkaline hydrolysis of brewer's spent grain
TL;DR: In this article, a full factorial design with three replicates at the center point was used to investigate the simultaneous effects of the variables: NaOH concentration (1.0, 1.5 and 2.0%, w/v), temperature (80, 100 and 120°C), and reaction time (30, 60 and 90 min), on the alkaline hydrolysis.
Journal ArticleDOI
Biological bleaching of chemical pulps
TL;DR: The use of oxidative enzymes from white-rot fungi, that can directly attack lignin, is a second-generation approach, which could produce larger chemical savings than xylanase but has not yet been developed to the full scale.

Characterization of a cellulase-free, neutral xylanase from Thermomyces lanuginosus CBS 288.54 and its biobleaching effect on wheat straw pulp.
TL;DR: A xylanase purified from the thermophilic fungus Thermomyces lanuginosus CBS 288.54 was characterized and its potential application in wheat straw pulp biobleaching was evaluated.

Production of xylanases from rice bran by Streptomyces actuosus A-151
San-Lang Wang,Yue-Horng Yen,Ing-Lung Shih,Audrey Chingzu Chang,Wen-Teish Chang,Wen-Chieh Wu,Yue-Der Chai +6 more
TL;DR: Results showed that Streptomyces actuosus A-151, isolated from northern Taiwan, produced β-xylanase when rice bran was used as the sole carbon source, and addition of xylan, shrimp and crab shell powder, and orange peel to the culture medium was found to enhance the production of x Dylanase.

Effect of enzymatic pretreatment on the diffusion of sodium hydroxide in wood
TL;DR: In this article, the effect of enzyme pretreatment of woods relative to the diffusion of sodium hydroxide was investigated, and the results showed that the diffusion coefficient was increased by at least 15% in hardwoods and by approximately 60% in southern pine.
