    • The 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 (110) 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.
    • PCT No.PCT / JP97 / 01949 Sec。 371日期:1998年5月27日 102(e)日期1998年5月27日PCT提交1997年6月9日PCT公布。 公开号WO97 / 48730 PCT 日期1997年12月24日本发明的目的是提供一种方便的方法,用于恢复BC的各种性质,即使其一旦干燥。 本发明涉及一种细菌纤维素的加工方法,其特征在于包括在搅拌培养基中随后进行均质化的细菌纤维素在张力下脱水和干燥,以及一种加工细菌纤维素的方法,该方法包括将搅拌的细菌纤维素 在平面取向度(h1 / h2)(其中h1和h2表示起始于结晶平面(1 + E,ov 1 + EE 0)和晶体平面(110)的峰的高度)的条件下的培养, 分别用通过反射法的X射线衍射法得到的衍射曲线)为2以上,进行均质化。 通过使用通过上述方法得到的细菌纤维素可以制备出具有高强度的填料和片材的优异助留剂。
