“…Similar phenomenon has been reported that adding extra β-glucosidase with CTec2 improved the glucose and xylose yields of glycerol treated Miscanthus straw from 12.5% and 4.2% to 88.8% and 68.5%, respectively [44]. In this work, relatively high content of cellobiose in the hydrolysate of HPAC-pretreated poplar could inhibit the hydrolytic capacity of xylanase in CTec2 and decreased the xylose yield [45].…”

“…Until now only acids have been used in XOS production, including mineral and organic acids (Zhang et al 2014 Recently, it has been found that gluconic acid (GA), a green and edible organic acid(Zhou and Xu 2019b), can release H + to e ciently pre-hydrolyze corncob, directly producing XOS in 54.3% yield. However, the methods that employ organic acids assist in depolymerization of the hemicellulose present in lignocellulosic biomass turning it into XOS, producing low concentration (Chen et al 2019;Wen et al 2020). Moreover, liquid phase from acidic hydrolysis of lignocellulosic biomass contains not only xylandegraded by-products but also cellulose and lignin such as formic acid, acetic acid HMF (Jiang et al 2013), phenolic compounds and crude proteins (Neto et al 2020).…”

“…Particularmente no caso da xilana, a desconstrução da cadeia principal a monômeros de Dxilose pode ser alcançada mediante a catálise por endo-1,4-β-xilanases e β-xilosidases (MÉNDEZ-LÍTER et al, 2021). As xilanases desempenham um papel fundamental nesse processo, uma vez que promovem o ataque inicial às ligações glicosídicas presentes no interior desse polímero, convertendo-o em xilooligossacarídeos (XOs) com diferentes graus de polimerização (CHEN et al, 2019a;HAN et al, 2019;HAQ & AKRAM, 2019;YANG et al, 2019;EVANGELISTA et al, 2018;AN et al, 2015).…”

“…Os XOs são produtos de alto valor agregado que podem ser potencialmente explorados como prebióticos ou, ainda, convertidos a xilose pelas β-xilosidases; esse açúcar, por sua vez, pode ser utilizado na produção de etanol 2G, xilitol, ácido lático, entre outros bioprodutos (MÉNDEZ-LÍTER et al, 2021;POLETTO et al, 2020;WU et al, 2019;EVANGELISTA et al, 2018;KUMAR et al, 2018a;AN et al, 2015;TURNER et al, 2015). Além disso, xilanases são biocatalisadores industrialmente relevantes para outros processos, incluindo o branqueamento de polpa de papel, a clarificação de sucos de frutas, a panificação, a finalização de cervejas, o tratamento de resíduos industriais e a degomagem de fibras têxteis (MÉNDEZ-LÍTER et al, 2021;BERNARDI et al, 2021a;CHEN et al, 2019a;de AMO et al, 2019;EVANGELISTA et al, 2018;AN et al, 2015). Todas essas possibilidades de aplicações biotecnológicas justificam a elevada quantidade de estudos sobre xilanases presentes na literatura e o crescente interesse por essa enzima.…”
