Abstract: The present invention includes compositions and methods for making and using halophilic cyanobacterium comprising a spontaneous mutation causing constitutive cellulose biosynthesis, whereby the cyanobacterium is capable of producing cellulose in brine. 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.

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.

Abstract: Methods and kits for decomposing organophosphorus compounds in non-aqueous media at ambient conditions are described. Insecticides, pesticides, and chemical warfare agents can be quickly decomposed to non-toxic products. The method comprises combining the organophosphorus compound with a non-aqueous solution, preferably an alcohol, comprising metal ions and at least a trace amount of alkoxide ions. In a first preferred embodiment, the metal ion is a lanthanum ion. In a second preferred embodiment, the metal ion is a transition metal.

Abstract: The present invention includes compositions and methods for the integration of a non-allergenic nanocellulose into a wound bed. The composition may be formed into a wide variety of implants, e.g., a suture, a sheet, a compress, a bandage, a band, a prosthesis, a fiber, a woven fiber, a bead, a strip, a clasp, a prosthesis, a catheter, a screw, a bone plate, a pin, a bandage or combinations thereof.

Abstract: The invention relates to optical sensors and systems and methods employing the sensors for detecting one or more compounds of interest in a test medium. In one embodiment an optical sensor comprising a long period grating and a solid phase microextraction (SPME) film is exposed to a test medium such that one or more compounds of interest are selectively partitioned into the solid phase microextraction film. At least one optical property of the sensor exposed to the test medium is compared with at least one corresponding optical property of the sensor in absence of the test medium; wherein a difference in the optical property is indicative of one or more compounds of interest in the test medium. The methods and systems may employ long period grating sensors with or without SPME films, and fiber loop ring-down spectroscopy to measure optical properties of the sensor.

Abstract: The present invention is a device, method and system for making a display and displaying information that includes a fibrous organic substrate, e.g., a cellulose or cellulose substrate, and a variable reflectivity dye disposed in the fibrous substrate, wherein the reflectivity of the dye is modulated in situ. The display device may use a dye selected from an electrochromic, a thermochromic, a magnetochromic, an ionochromic, a light sensitive, a fluorescent, a fluorescent effect energy transfer dye or combinations thereof and may be used as high storage, high contrast and/or high definition paper.
