THE FORMATION OF CELLULOSE MICROFIBRILS IN SUSPENSIONS OF ACETOBACTER XYLINUM
Canadian Journal of Microbiology, 1960Formation of cellulose microfibrils from precursors elaborated by Acetobacter xylinum takes place remote from the cell surface and without an extensive, amorphous, intermediate high polymer. The microfibrils increase in mass by growth only at one or both tips. The rate of microfibrillar growth per bacterial cell at 25 °C is constant at 0.1 μ per minute

AbstractTwo types of microfibrillated cellulose (MFC) were prepared using either a sulfite pulp containing a high amount of hemicellulose (MFC 1) or a carboxymethylated dissolving pulp (MFC 2). MFC gels were then combined with amylopectin solutions to produce solvent‐cast MFC‐reinforced amylopectin films.

Periodic Disorder along Ramie Cellulose Microfibrils
Biomacromolecules, 2003Small angle neutron scattering studies have been carried out on cellulose fibers from ramie and Populus maximowicii (cotton wood). Labile hydrogen atoms were replaced by deuterium atoms, in water-accessible disordered regions of the fibers, to increase the neutron scattering contrast between the disordered and crystalline regions.

Morphological Structure of Cellulose Microfibrils
1985The 0.39 nm resolution lattice images of cellulose microfibrils in the cell wall of Valonia macrophysa could be successfully recorded from microfibrils prepared by disintegration as well as ultrathin sectioning. The results obtained from direct imaging of lattice lines contradict the models of the microfibrils in which the crystalline sub-elements ...

The ultrastructure and morphology of potato (Solanum tuberosum L.) tuber cells were investigated by optical, scanning, and transmission electron microscopies. After removal of starch granules, pectins and hemicelluloses were solubilized under alkaline conditions.

The Structure of Cellulose Microfibrils in Valonia
1982It is well known that cellulose is the main consitutent of plant-cell walls and that it exists as thin threads of indefinite length called microfibrils. The cellulose microfibril is an important factor influencing the chemical, physical, and mechanical properties of the cell walls, and it will give a clue to an understanding of how cellulose ...

Cellulose microfibril assembly and orientation: recent developments
Journal of Cell Science, 1985ABSTRACT A brief history of the literature dealing with cellulose microfibril assembly is presented, and a current summary of cellulose microfibril synthesizing complexes among eukaryotic cells is given. Terminal complexes not described before include the following: linear terminal complexes (TCs) with three rows in Eremosphaera ...

Microfibrillated cellulose based nanomaterials
Nanomatériaux à base de nanofibrilles de cellulose La cellulose étant l'un des biopolymères les plus abondants, elle est employée dans ce travail de thèse sous sa forme nano-fibrille (2 à 5nm de diamètre et plusieurs microns de long) pour préparer des nanomatériaux durables.
