Figure 5: The effect of protease, xylanase, and mannase on the ramie degumming for 4 h: (a) control pectinase; (b) control pectinase + mannase; (c) control pectinase + xylanase; (d) control pectinase + protease; (e) control pectinase + mannase + xylanase + protease. Control: fibers treated with glycine-NaOH buffer, mannase, xylanase, protease and mixture of mannase, xylanase, and protease under the same conditions for (a), (b), (c), (d), and (e), respectively.
