Hydrogen bonds and twist in cellulose microfibrils [PDF]

Carbohydrate Polymers, 2017
There is increasing experimental and computational evidence that cellulose microfibrils can exist in a stable twisted form. In this study, atomistic molecular dynamics (MD) simulations are performed to investigate the importance of intrachain hydrogen bonds on the twist in cellulose microfibrils.

Multiscale structure of cellulose microfibrils in regenerated cellulose fibers

Carbohydrate Polymers, 2023
Cellulose in solution can be assembled into textile fibers by wet-spinning (Viscose etc.) or dry-jet wet spinning (Lyocell, Ioncell etc.), which leads to significant differences in the mechanical properties of fibers. We use scanning X-ray microdiffraction (SXM) to reveal regenerated fibers having a "skin-core" morphology.

Dissecting the molecular mechanism underlying the intimate relationship between cellulose microfibrils and cortical microtubules

Frontiers in Plant Science, 2014
A central question in plant cell development is how the cell wall determines directional cell expansion and therefore the final shape of the cell. As the major load-bearing component of the cell wall, cellulose microfibrils are laid down transversely to ...

Structure of cellulose microfibrils in mature cotton fibres [PDF]

Carbohydrate Polymers, 2017
The structure of cellulose microfibrils in mature cotton fibres from three varieties - Gossypium hirsutum, G. barbadense and G. arboreum - has been investigated by a multi-technique approach combining small angle scattering techniques with spectroscopy and diffraction.

Structural changes in sugarcane bagasse cellulose caused by enzymatic hydrolysis

Journal of Wood Science, 2020
Cellulose I is not completely saccharified to glucose at a low cellulase concentration. In this study, sugarcane cellulose saccharification residues were investigated.

Direct Measurement of Plant Cellulose Microfibril and Bundles in Native Cell Walls

Frontiers in Plant Science, 2020
Plants use rigid cellulose together with non-cellulosic matrix polymers to build cell walls. Cellulose microfibrils comprise linear β(1,4)-glucan chains packed through inter- and intra-chain hydrogen-bonding networks and van der Waals forces.

Production of Cellulose Microfibrils by Rhizobium [PDF]

Applied Microbiology, 1975
Electron microscope examination of Rhizobium spp. revealed microfibrils produced by flocculating strains but not by nonflocculating strains. The microfibrils from R. trifolii (NA30) were isolated and identified as cellulose by enzymatic, X-ray diffraction, and infrared spectral analyses. Both
