Optimization of Microbial Cellulose Production by the Newly Isolated Acetobacter sp. DR-1 under Laboratory Conditions
Abstract: Cellulose is the most abundant natural biopolymer on the earth, synthesized by plants, algae and also some species of bacteria. It is also produced by some animals (e.g., tunicates).Cellulose constitutes one of the three principal components present in plant, namely cellulose, hemi-cellulose and lignin. However, the degree of polymerization and crystallinity of bacterial cellulose is considerable high than that of plant cellulose. In microbes, cellulose is normally produced as exo-polysaccharide, …
