Table 1 Carbohydrates released from pretreated wheat straw and giant reed by xylan-acting enzymes after 24 h hydrolysis in 50 mM sodium citrate buffer at pH 5.0 and 45°C

From: The role of acetyl xylan esterase in the solubilization of xylan and enzymatic hydrolysis of wheat straw and giant reed

Substrate Enzyme preparation Xylose Xylobiose Xylotriose Xylotetraose Total
Wheat straw XYL 1.6 7.2 1.0 bdl 9.8
  XYL+ARA 1.6 8.0 1.2 bdl 10.8
  XYL+AXE 2.2 9.1 bdl bdl 11.3
Giant reed XYL 1.7 7.5 2.3 1.7 13.2
  XYL+ARA 1.6 7.3 2.3 1.8 13.0
  XYL+AXE 3.1 10.6 bdl bdl 13.7
  1. The results are expressed as % of xylan (as xylose) in wheat straw or giant reed. The values of xylobiose, xylotriose and xylotetraose contained both acetylated and non-acetylated xylo-oligosaccharides. ARA: α-L-arabinofuranosidase; AXE: acetyl xylan esterase; bdl: below detection limit; XYL: xylanase.
