Figure 3From: Positional preferences of acetyl esterases from different CE families towards acetylated 4-O-methyl glucuronic acid-substituted xylo-oligosaccharides Acetic acid assay. Acetic acid released as proportion (%) of the total amount of acetic acid present in acetylated 4-O-methyl glucuronic acid (MeGlcA)-substituted xylo-oligosaccharide (AcUXOS) after an incubation time of 16 h, at pH 5.0 and 50°C.Back to article page
