Pectinase for Cotton Stalk Degumming Bast Fiber of Biological Research

Based on the chemical constituents of cotton stalk phloem quantitative analysis is done.Pectinase preparation for cotton stalk bast fiber impact single-factor experiments and L9(34) orthogonal test to optimize use of pectinase Degumming and simple preparation of chemical treatment combined a cotton stalk bast fiber technology.Research: pH4.0,enzyme concentration of 5 g.L-1,temperature 40 ℃,time 96h enzymatic conditions,can remove the cotton stalk bast lignin 43.6% pectin 25.1%,the preparation of cotton stalk phloem technology fiber fineness 3.35 ~ 3.65 tex;the average length of 84.5mm.
