Abstract
A method and media for producing bacterial cellulose under agitated culture conditions resulting in sustained production over an average of 70 hours of at least 0.1 g/liter per hour are achieved. A unique reticulated cellulose product is produced using the methods and conditions claimed, and may be converted to of a sheet characterized by substantial resistance to densification and great tensile strength when produced by sheet forming means. Acetobacter strains are identified as stable under agitated culture conditions and exhibit substantially reduced gluconic and keto-gluconic acids production.
