Cellulose is the main constituent of the structureof plants (natural polymer) that, whenextracted, is employed for making paper,plastics, and in many combinations. Celluloseis made up of long-chain molecules inwhich the complex unit C6H10O5 is repeatedas many as 2000 times. It consists of glu...
Bacterial cellulose(BC) is an environmentally-friendly polymeric material, which is now receiving increased attention in human society. It is an unbranched polymer with nanofibrils, made up of (1→4)β-glycosidic linked glucose units. These linearglucanchains form highly regular intra- and inter mo...
Paper is made up of layers (1 -3) of cellulose fibers (5). It contains cellulose granules (6) which form additional capillaries (7). The granules have a diameter of 50 -6000, especially 150 - 1000 microns.SCHLOSSER HARALD
The glycosynthase is a mutant cellulase in which the catalytic nucleophile required in trans-glycosylation by the wild-type enzyme was replaced by a non-nucleophilic residue (Faijes and Planas, 2007; Shaikh and Withers, 2008). The glycosynthase catalyzes the build-up of cellulose chains from an...

morphology and biochemical composition of the plant. Man-made cellulose fibers are produced by pursuing different methods that include a first dissolution followed by the actual process. Although the production of pure cellulose fibers is still challenging, wet-, dry-, dry-jet-wet and electrospinning...
Cellulose acetate is produced by substituting the hydroxyl groups of the cellulose acetyl units (Fig. 12.8). The obtaining of cellulose acetate is possible through the reaction of cellulose with a mixture of acetic acid and acetic anhydride, in the presence of sulfuric acid, perchloric acid, or ...
Ionic liquid (IL) is one of the pretreatment processes gaining considerable interests to remove the native recalcitrance of lignocellulose. But the cellulose crystalline transformation during the pretreatment and their correlations with enzymatic digesti
