Structure of Cellulose Microfibrils in Primary Cell Walls from Collenchyma1[C][W][OA]

Plant Physiology, 2012
In the primary walls of growing plant cells, the glucose polymer cellulose is assembled into long microfibrils a few nanometers in diameter. The rigidity and orientation of these microfibrils control cell expansion; therefore, cellulose synthesis is a ...

Cellulose microfibril-water interaction as characterized by isothermal thermogravimetric analysis and scanning electron microscopy [PDF]

BioResources, 2012
Microfibrillated celluloses, liberated from macroscopic lignocellulosic fibers by mechanical means, are sub-fiber elements with lengths in the micron scale and diameters ranging from 10 to a few hundred nanometers. These materials have shown strong water

Cellulose biosynthesis in plants - the concerted action of CESA and non-CESA proteins

Biologia Plantarum, 2020
Cellulose is the most abundant polysaccharide produced by plants. In the form of rigid microfibrils surrounding the cells, cellulose constitutes the load-bearing cell wall element that controls cell growth and shape.

Melt Processing of Cellulose Acetate for Controlled Release Applications – A Review

Macromolecular Materials and Engineering, EarlyView.
This review presents recent developments in the melt‐processing of cellulose acetate (CA). Factors affecting the processability, biodegradability, and mechanical performance of CA are also summarized. Plasticizers, bio‐based polymers (PLA, PBAT & PHBV), and clay nanoparticles are also examined toward enhancing the melt processability and mechanical ...

Giardia Cyst Wall Protein 1 Is a Lectin That Binds to Curled Fibrils of the GalNAc Homopolymer [PDF]

, 2010
The infectious and diagnostic stage of Giardia lamblia (also known as G. intestinalis or G. duodenalis) is the cyst. The Giardia cyst wall contains fibrils of a unique β-1,3-linked N-acetylgalactosamine (GalNAc) homopolymer and at least three cyst wall ...

Resonant soft X-ray scattering reveals cellulose microfibril spacing in plant primary cell walls

Scientific Reports, 2018
Cellulose microfibrils are crucial for many of the remarkable mechanical properties of primary cell walls. Nevertheless, many structural features of cellulose microfibril organization in cell walls are not yet fully described.

Mesenchymal Stem Cell‐Engrafted Bacterial Cellulose and Graphene Oxide Scaffolds Enhance Peripheral Nerve Repair in a Rat Model

Macromolecular Materials and Engineering, EarlyView.
This study investigates the use of graphene oxide‐decorated bacterial cellulose (BC/GO) scaffolds combined with mesenchymal stem cells (MSCs) to enhance axonal regeneration after sciatic nerve injury in rats. Graphene oxide is embedded monodispersely into the BC fibrillar matrix.

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.
