ABSTRACT:
delete-start id="DEL-S-00001" date="20050906" ?This invention provides a bacterial cellulose comprising ribbon-shaped microfibrils having a thickness of 10 to 100 nm and a width of 160 to 1000 nm or a bacterial cellulose comprising ribbon-shaped microfibrils having a thickness of 10 to 100 nm and a width of 50 to 70 nm. The former bacterial cellulose can be produced by culturing cellulose-producing bacteria in a culture medium containing a cell division inhibitor, and the latter can be produced by culturing the bacterium in a culture medium containing an organic reducing agent. The bacterial cellulose is modified from conventional bacterial cellulose in the major axis, and is improved in Young's modulus, etc.delete-end id="DEL-S-00001" ?insert-start id="INS-S-00001" date="20050906" ?This invention provides a bacterial cellulose comprising ribbon-shaped microfibrils having a thickness of 1 to 9 nm and a width of 160 to 1000 nm or a bacterial cellulose comprising ribbon-shaped microfibrils having a thickness of 1 to 9 nm and a width of 50 to 70 nm.
