Abstract
The present invention includes compositions and methods for making and using an isolated cyanobacterium that includes a portion of an exogenous bacterial cellulose operon sufficient to express bacterial cellulose, whereby the cyanobacterium produces extracellular glucose. The compositions and methods of the present invention may be used as a new global crop for the manufacture of cellulose, CO2 fixation, for the production of alternative sources of conventional cellulose as well as a biofuel and precursors thereof.
Claims6
An isolated Synechococcus leopoliensis strain UTCC100 cyanobacterium comprising an exogenous bacterial cellulose operon from Acetobacter xylinum NQ5 comprising the acsAB operon sufficient to express bacterial cellulose, wherein the cyanobacterium is capable of secreting extracellular monosaccharides, disaccharides, oligosaccharides or polysaccharides.
