ABSTRACT
Cellulose is the most abundant natural organic polymer existing as a main plant cell wall component and is important as a biodegradable and renewable organic resource [ 1]. The study of cellulose, therefore, has continued for more than 150 years. However. there are stiJJ several problems which should be solved: biosynthesis. crystal structure. chemical synthesis, regiospecific substitution reactions. structure-function relationships of their derivatives. and so on [ I ,2].
