Project TitleInvestigation of Bacterial Cellulose (BC) based "Green" Composites
Track Code4792
Short Description

Cornell researchers have developed a method of greatly decreasing the production cost of bacterial cellulose (BC), opening the door to low-cost environmentally-friendly nano-composites

Abstract

Cornell researchers have developed a method of greatly decreasing the production cost of bacterial cellulose (BC), opening the door to low-cost environmentally-friendly nano-composites.  BC is produced by Acetobacter xylinum bacteria in a fermentation medium and, though completely biodegradable and with the same chemical structure as plant-based cellulose, its nanometer-sized fibers have very high strength and purity, and can be adapted to a wide variety of applications.  These include composite membranes, which can be greatly strengthened by the addition of micro- and nano-cellulose fibers during production.  To date, the high cost of BC production has been a major factor in limiting its use, but the process developed at Cornell allows the use of inexpensive carbon sources to greatly reduce cost while maintaining BC's advantages.  The process promises to benefit a wide variety of industries using cellulose and composites.
