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 II product is produced using the methods and conditions claimed, and may be in the form of a sheet characterized by resistance to densification and great tensile strength when produced by sheet forming means. Also strains of Acetobacter that are stable under agitated culture conditions and that exhibit substantially reduced gluconic and keto-gluconic acids production are described.
