“…Actually, the most common XOs produced by enzymatic hydrolysis from previously reported endo‐xylanases are X2 and X3 . Interestingly, the endo‐xylanase AfXynB that we described herein exhibited a new hydrolytic property compared to the other reported endo‐xylanases, and it could hydrolyze the beechwood xylan to only yield X2 and X5.…”

“…apresentam maior atividade na faixa de pH de 4,5 -6,0 (Tabela 6). Os valores obtidos neste trabalho são similares a outros trabalhos, como as xilanases purificadas a partir de Aspergillus niger (pH 5,0), Aspergillus terreus (pH 5,0) e Aspergillus fumigatus (pH 5,0) (Krisana et al, 2005;Yang et al, 2015).…”

“…15 Acidic xylanase activity was measured by evaluating acidic xylanase reduction of xylan to monosaccharides under acidic conditions, resulting in a colorchange of 3,5-dinitrosalicylic acid (DNS) with the monosaccharides in aqueous solutions that can then be used to calculate acidic xylanase activity. 16 Cellulase activity was measured using anthrone colorimetry. 17 2.2.2 Harvesting, determination of agronomic traits, and biological efficiency.…”
