Abstract:
A method for producing substantially reticulated cellulose comprising:a) culturing a microorganism of the genus Acetobacter or mutants thereof, wherein said microorganism is capable of producing substantially pure cellulose, under substantially continuous agitation in a liquid medium suitable for growth of said microorganism for a sufficient time to produce reticulated cellulose, said microorganism being characterized as being stable against conversion from cellulose producing forms to non-cellulose producing forms under said culturing conditions; andb) recovering said reticulated cellulose produced from said culturing, wherein said cellulose is characterized when viewed with a scanning electron microscope by a reticulated structure having strands of cellulose that interconnect forming a grid-like pattern extending in three dimensions to give a fenestrated appearance.
