Fig. 4From: In silico screening and experimental analysis of family GH11 xylanases for applications under conditions of alkaline pH and high temperatureActivity assay of xylanases Xyn1, Xyn3, Xyn5 and Xyn8 with 1% oat-spelt xylan as the substrate, carried out by measuring reducing sugars with the DNS method. Assays at different pH values (a) were conducted at 65 °C. Assays at different temperatures (b) were conducted at pH 9.0. Error bars indicate standard deviation of triplicatesBack to article page
