“…Pretreatment with a commercial enzyme (Xylanase-P) increased the brightness of bagasse pulp by 3.1% and softwood kraft pulp by 5.1% compared to control after ECF bleaching (Madlala et al, 2001). Campioni et al (2019) performed the pretreatment of Eucalyptus kraft pulp with T. reesei QM9414 xylanase and observed a 10% reduction in chlorine dioxide consumption, maintaining the same brightness as in control.…”

“…Filamentous fungi are well known for the production of xylanases in the large amount. The xylanases from different species related to the genus Aspergillus, Trichoderma, Penicillium, Coprinellus, Humicola, Thermomyces have been used for biobleaching of pulp (Bissoon et al, 2002, Lal et al, 2011, Kumar V et al, 2016, Campioni et al 2019, Chaurasia & Bhardwaj, 2019. Several species of the genus Aspergillus such as A. niger, A.…”

“…This increases the permeability of pulp fiber surfaces and improves the penetration of bleaching chemicals into the pulp. So, xylanase action assists the removal of trapped lignin from pulp fiber rather than attacking lignin directly (Motta et al, 2013;Campioni et al,. 2019).…”

Environmental pollution can be minimized by using xylanase pretreatment of pulp before chemical bleaching. A. flavus ARC-12 and S. commune ARC-11 produced 234.26 and 1147.11 IU/ml of xylanase under solid-state fermentation that was used for biobleaching of ethanol-soda pulp of Eulaliopsis binata. The brightness of bleached ethanol-soda pulp of E. binata increased by 3.2 and 1.9% (ISO) with A. flavus ARC-12 and S. commune ARC-11 xylanase respectively compared chemical bleaching at the same chlorine dioxide charge. While the consumption of chlorine dioxide were mitigated by 2.98 and 3.82% with A. flavus ARC-12 and S. commune ARC-11 xylanase pretreatment respectively. Moreover, A. flavus ARC-12 and S. commune ARC-11 xylanase pretreatment reduced AOX generation by 23.80 and 19.04% respectively compared to chemical bleaching.

“…Regarding the xylanase application on kraft pulp biobleanching, Campioni et al (2019) studied xylanase extract produced by T. reesei QM9414 in SmF with SS and optimized the biobleanching parameters. The best conditions were 30 U/g of xylanase, at pH 5, at 50 °C during 30 min and resulted a 12.5% of Kappa number reduction.…”

Sugarcane straw (SS) was used in an economic biosystem to evaluate the production of xylanases and cellulases in submerged fermentation (SmF) by axenic and mixed mode from Trichoderma and Aspergillus species. T. reesei QM9414 axenic culture reached the highest xylanase production (90.2 U/mL) and 0.5 FPU/mL of cellulase activity. The evaluation of agro-industrial residues on fibrolytic enzymes production was performed by a D-optimal design, and revealed the best supplementation of 100% SS, while wheat bran and citric pulp showed lower inductive effects on enzymes production. Also, the scale-up in a stirred tank showed the same yield production profile (xylanase ~ 90 U/mL and celullase 0.6 FPU/mL). Xylanase was characterized by an optimum pH of 5-6 and temperature at 50 ºC, and thermal stability was below 50 ºC. The ion Mn2+ (5 and 10 mM) had a stimulatory effect on xylanase activity. The biobleaching application showed that 30 U/g of xylanases during 15 min decreased Kappa number in 9.37. These results indicate SS as an alternative substrate for fungi fibrolytic enzymes production and the xylanase with low cellulase extract as a potential biobleaching application.

“…All procedures for FEE production were performed at Institute of Bioenergy Research (IPBEN), São Paulo State University, Assis, SP, Brazil. The production of the enzyme extract followed the recommendations of Campioni, Moreira, Moretto, Nunes, and Oliva Neto (2019). The enzyme activity was determined according to the methods described by Wood and Bhat (1988) for endoglucanase (EC 3.2.1.4.)…”

During specific times of the year, especially dry seasons, tropical forages typically have poor nutritional value due to high contents of neutral and acid detergent fibres, and low crude protein in their composition, which may reduce productivity of ruminant livestock production and lead to increased enteric methane (CH4) emissions per unit of generated product in forage‐bases systems. In order to increase fibre degradability and the efficiency of energy utilisation from low‐quality forages, exogenous fibrolytic enzymes have been studied. In this assay, we evaluated the effects of increasing dose levels of fibrolytic enzymes extract (FEE) produced by Trichoderma reesei on in vitro rumen organic matter degradability, fermentation parameters, total gas and CH4 production of tropical forages. Forage samples were analysed for their bromatological composition, and enzyme activity from FEE was performed for xylanase and endoglucanase. The in vitro gas production technique was used in a 5 × 3 factorial arrangement with five FEE dose levels (0, 5, 50, 500 and 5,000 µl) and three substrates (Cynodon spp., Panicum maximum and Cenchrus ciliaris L.). The highest dose level of FEE increased degradability, total gas and CH4 production in all substrates (p < .05). Butyrate concentration also increased while acetate:propionate ratio and pH decreased with the addition of FEE (p < .05). These results indicated that the use of fibrolytic enzymes can be a reliable strategy to improve degradability of low‐quality forages, contributing to the sustainability and intensification of livestock production in tropical countries.
