113. Abstract

The purpose of this review is to examine the different forms and sources of cellulose as they may apply to potential industrial utilization. Various macromolecular parameters of cellulose, including microfibrillar shape and form, orientation of cellulose within the cell wall, on the cell surface, or in the medium, will be described. In this context, cellulose of great tensile strength and high crystallinity will be discussed. These celluloses come from giant algal cells such as Valonia and Boergesenia. The relationship of the microfibrillar structure and its physical properties to the structure and geometry of the cellulose synthesizing complex will be presented. Cellulose can also be deposited not as a cell wall, but in the extracellular medium in the form of spikes, ribbons, threads, or tubes. Organisms such as Dictyostelium, Dinobryon, and Acetobacter will be described. The particular advantages and uses of bacterial cellulose will be covered and compared with conventional sources such as woody tissues and cotton fibers. A knowledge of the molecular and cellular levels of organization may provide guidance for the screening of potential industrial cellulose-producing sources in the future, including in vitro cellulose synthesis. Guidelines towards these goals will be presented.
