PCT No. PCT/JP97/01949 Sec. 371 Date May 27, 1998 Sec. 102(e) Date May 27, 1998 PCT Filed Jun. 9, 1997 PCT Pub. No. WO97/48730 PCT Pub. Date Dec. 24, 1997The purpose of the present invention is to provide a convenient method for restoring the various properties of BC even after it is once dried. The present invention relates to a method for processing a bacterial cellulose comprising dehydrating and drying under tension the bacterial cellulose produced in an agitated culture followed by homogenization, and to a method for processing a bacterial cellulose comprising dehydrating and drying the bacterial cellulose produced in an agitated culture under such conditions that a degree of planar orientation (h1/h2) (wherein h1 and h2 mean the height of a peak originating in the crystallographic plane (1+E,ovs 1+EE 0) and the crystallographic plane (110), respectively, in a diffraction curve obtained with X-ray diffractometry by a reflection method) will be 2 or more, followed by homogenization. An excellent retention aid for fillers and sheet with a high strength may be prepared by using the bacterial cellulose obtained by the above methods.
