Research Progress in Friendly Environmental Technology for the Production of Cellulose Products (Bacterial Cellulose and Its Application)

Abstract

Recently, an environmental criteria was required for every product and process. The great amount of pollution caused by the paper and cellulose industry effluents, especially those produced from nonwood fibrous materials, e.g., rice straw and bagasse. Using new technologies or redesigning products to meet new environments criteria is necessary. The production of cellulose by microorganisms is considered as one of the most beneficial sources for environment requirements. Microbial polysaccharides are valuable commodities, since they display many useful properties and can be produced in large quantities. This article reviews previous research on the biosynthesis of bacterial cellulose, structural features, properties, as well as potential applications as new industrial materials, i.e., paper industry, wastes treatment, sewage purification, food, medicine, etc. Suggestions for an economic production process for bacterial cellulose and cellulose derivatives also were reported.
