Cellulose and Paper Department, National Research Center, Dokki, Cairo (Egypt) Heterogeneous derivatizations, e.g. carboxymethylation and cyanoethylation were performed on bacterial cellulose (BC), viscose grade pulp and cotton linters (plant celluloses) to reveal their chemical reactivity. IR spectroscopy of these derivatives revealed that the relative absorbance of ether linkage in BC is of lower value than that of viscose grade pulp and cotton linters. This indicates a lower degree of polymerization (DP) in BC than in the other two kinds of cellulose, which reflects the higher reactivity of BC toward cyanoethylation and carboxymethylation. https://www.biotech-asia.org/vol1no1/heterogeneous-derivatization-of-bacterial-and-plant-cellulose/ Bacterial cellulose; Gluconacetobacter xylinus; Viscose grade pulp
