Cellulose is well known as one of the most abundant biodegradable materials in nature and has received considerable interest in both academic and industrial fields. Cellulose synthesized by bacteria is of particular interest over plant cellulose for some applications due to its unique structural and mechanical properties and high purity.

Some high value applications for bacterial cellulose include biomedical applications (scaffold for tissue engineering, wound dressing materials, artificial skin), and production of membranes for high tech applications, such as diaphragms for loudspeakers.

Problem: Bacterial cellulose is currently expensive to produce and purchase however, due to the expense of the media.

Solution: Use inexpensive hot water extracted wood sugars for bacterial cellulose production.
