The spatial orientation and interaction of cell wall polymers in bamboo revealed with a combination of imaging polarized FTIR and directional chemical removal

The mechanical and physical properties of lignocellulosic materials are closely related to the orientation interaction polymers within cell walls. In this work, Imaging Polarized FTIR, combined with directional chemical removal, was applied characterize spatial wall in bamboo fibers parenchyma cells from two species. results demonstrate cellulose is nearly axially oriented whereas it almost transversely arranged cells. Xylan lignin both preferentially alongside cellulose, but less degree After average xylan little affected, suggesting a strong between xylan. However, alkaline treatment significantly weakens cells, more significant for latter, indicating easy-degradable nature Additionally, seemed were difficult remove as compared supporting assumption that stronger exists fibers. word, believed suitable biorefinery owing their ordered relatively loose molecular assembly,
