Rohstoff zur Papierherstellung, der zu 90 % aus Zellulose besteht, gewonnen aus Holz, Stroh, Baumwolle, Flachs u.a.
Complex carbohydrate composed of long chains of glucose units, joined by chemical bonds called glycosidic links. It is the principal constituent of the cell wall of higher plants, and a vital ingredient in the diet of many herbivores. Molecules of cellulose are organized into long, unbranched microfibrils that give support to the cell wall. No mammal produces the enzyme cellulase, necessary for digesting cellulose; mammals such as rabbits and cows are only able to digest grass because the bacteria present in their gut can manufacture it.
Cellulose is the most abundant substance found in the plant kingdom. It has numerous uses in industry: in rope-making; as a source of textiles (linen, cotton, viscose, and acetate) and plastics (cellophane and celluloid); in the manufacture of nondrip paint; and in such foods as whipped dessert toppings.
A polysaccharide that is the chief constituent of all plant tissues and fibers.

Als Rohmaterial für die Gewinnung von Z. verwendet man in erster Linie Holz (Fichte, Kiefer, Buche), aber auch Stroh, Kartoffelkraut u. Bastfasern.
