Abstract
Acetobacter strains are identified as stable under agitated culture conditions and exhibit substantially reduced gluconic and keto-gluconic acids production. 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. Preferred Acetobacter strains are ATCC Nos. 53264, 53263 and 53524.
