Patent number: 7943349Abstract: A novel modified thermoplastic starch is manufactured from a native starch using a polysaccharide produced by the fungus species Ophiostoma ulmi, by growing a culture in a yeast extract medium; adding the native starch; mixing, and harvesting the modified thermoplastic starch. The modified thermoplastic starch may be used in the manufacture of a biodegradable plastic which exhibits low water absorbency and high tensile strength. The plastic may be used to manufacture films or molding products by casting, extrusion, injection, or compression techniques.Type: GrantFiled: June 18, 2007Date of Patent: May 17, 2011Inventors: Mohini Sain, Robert Jeng, Martin Hubbes

Publication number: 20110086386Abstract: A method of fractionating biomass, by permeability conditioning biomass suspended in a pH adjusted solution of at least one water-based polar solvent to form a conditioned biomass, intimately contacting the pH adjusted solution with at least one non-polar solvent, partitioning to obtain an non-polar solvent solution and a polar biomass solution, and recovering cell and cell derived products from the non-polar solvent solution and polar biomass solution. Products recovered from the above method. A method of operating a renewable and sustainable plant for growing and processing algae.Type: ApplicationFiled: December 8, 2010Publication date: April 14, 2011Inventors: Thomas J. Czartoski, Robert Perkins, Jorge L. Villanueva, Glenn Richards

Patent number: 7915017Abstract: A process for the treatment of biomass to render structural carbohydrates more accessible and/or digestible using concentrated ammonium hydroxide with or without anhydrous ammonia addition, is described. The process preferably uses steam to strip ammonia from the biomass for recycling. The process yields of monosaccharides from the structural carbohydrates are good, particularly as measured by the enzymatic hydrolysis of the structural carbohydrates. The monosaccharides are used as animal feeds and energy sources for ethanol production.Type: GrantFiled: September 17, 2007Date of Patent: March 29, 2011Assignee: Board of Trustees of MICHIGAN STATE UNIVERSITYInventor: Bruce Dale
