Fig. 7From: In silico screening and experimental analysis of family GH11 xylanases for applications under conditions of alkaline pH and high temperatureAnalysis of reducing sugars after application of hybrid xylanases Xyn5–CBM2 and Xyn5–CBM9 to alkali pre-treated rice straw. a Reducing sugars were measured by the DNS method, after 24 h digestion at the indicated conditions of pH and temperature. C (Control) correspond to treated rice straw not subjected to enzyme treatment. Error bars represent standard deviation among three replicates. b Chromatographic profile of products obtained after application of xylanases to alkali-treated rice straw, as before. Peaks 1, 2 and 3 correspond to xylose, xylobiose, and xylotriose, respectively. Other relatively abundant, unidentified products are marked with an asteriskBack to article page
