Homogenization of a system of elastic and reaction-diffusion equations modelling plant cell wall biomechanics [PDF]

, 2015
In this paper we present a derivation and multiscale analysis of a mathematical model for plant cell wall biomechanics that takes into account both the microscopic structure of a cell wall coming from the cellulose microfibrils and the chemical reactions

Xyloglucan Is Not Essential for the Formation and Integrity of the Cellulose Network in the Primary Cell Wall Regenerated from Arabidopsis Protoplasts

Plants, 2020
The notion that xyloglucans (XG) play a pivotal role in tethering cellulose microfibrils in the primary cell wall of plants can be traced back to the first molecular model of the cell wall proposed in 1973, which was reinforced in the 1990s by the ...

Correlating macroscopic plant growth parameters to nanomechanical properties of cellulose microfibrils

Current Plant Biology
The plant cell wall, a vital component in providing structural integrity and facilitating growth, comprises cellulose microfibrils among its major constituents.

Subcritical crack growth in fibrous materials [PDF]

, 2006
We present experiments on the slow growth of a single crack in a fax paper sheet submitted to a constant force $F$. We find that statistically averaged crack growth curves can be described by only two parameters : the mean rupture time $\tau$ and a ...

Cellulose Microfibril Formation by Surface-Tethered Cellulose Synthase Enzymes

ACS Nano, 2016
Cellulose microfibrils are pseudocrystalline arrays of cellulose chains that are synthesized by cellulose synthases. The enzymes are organized into large membrane-embedded complexes in which each enzyme likely synthesizes and secretes a β-(1→4) glucan.

Overproduction of native endo-β-1,4-glucanases leads to largely enhanced biomass saccharification and bioethanol production by specific modification of cellulose features in transgenic rice

Biotechnology for Biofuels, 2019
Background Genetic modification of plant cell walls has been implemented to reduce lignocellulosic recalcitrance for biofuel production. Plant glycoside hydrolase family 9 (GH9) comprises endo-β-1,4-glucanase in plants.

Solid-state NMR investigations of cellulose structure and interactions with matrix polysaccharides in plant primary cell walls [PDF]

, 2015
Until recently, the 3D architecture of plant cell walls was poorly understood due to the lack of high-resolution techniques for characterizing the molecular structure, dynamics, and intermolecular interactions of the wall polysaccharides in these ...

Electron tomography unravels new insights into fiber cell wall nanostructure; exploring 3D macromolecular biopolymeric nano-architecture of spruce fiber secondary walls

Scientific Reports, 2023
Lignocellulose biomass has a tremendous potential as renewable biomaterials for fostering the “bio-based society” and circular bioeconomy paradigm. It requires efficient use and breakdown of fiber cell walls containing mainly cellulose, hemicellulose and

Pipe rheology of microfibrillated cellulose suspensions [PDF]

Cellulose, 2019
In this paper, we analyse the shear rheology of suspensions of two MFC grades in the consistency ranges of 0.2% to 1.5% and 0.5% to 2.0% with a pipe rheometer combined with ultrasound velocity profiling. In addition to yield stress and shear viscosity, we study the slip behaviour of the MFC suspensions, as this topic has so far been mostly neglected in

Isolation of Cellulose Nanofibers: Effect of Biotreatment on Hydrogen Bonding Network in Wood Fibers

International Journal of Polymer Science, 2011
The use of cellulose nanofibres as high-strength reinforcement in nano-biocomposites is very enthusiastically being explored due to their biodegradability, renewability, and high specific strength properties. Cellulose, through a regular network of inter-
