  • The present invention provides for novel compositions and methods for recycling or recovering ionic liquid used in IL pretreated cellulose and/or lignocellulosic biomass (LBM).
  • Self-setting compositions are formed by bringing into admixture an organic polyisocyanate, a non-ionic surface active agent devoid of isocyanate-reactive groups, an alkaline filler and water. Preferred alkaline fillers are portland cement, calcium oxide and hydrated lime. A plasticizer is preferably incorporated in the composition. Waste material, for example liquid or particulate radioactive wastes may be formed into a self-setting composition for consolidation and disposal. A particulate extender may be incorporated in the self-setting composition to give a product useful for example as a floor screed or cavity filler.
  • The present application discloses the identification of novel I. orientalis ADH1, ADHa, and ADHb genes, and the production and characterization of genetically modified yeast cells in which these genes were altered. Provided herein are isolated I. orientalis ADH1, ADHa, and ADHb polynucleotides and polypeptides, genetically modified yeast cells that overexpress I. orientalis ADH1 and/or contain deletions or disruptions of ADHa and/or ADHb, and methods of using culturing these modified cells to produce ethanol.
  • The present invention provides for a composition comprising a solution comprising (a) an ionic liquid (IL) or ionic liquid-aqueous (ILA) phase and (b) an organic phase, wherein the solution comprises a sugar and a boronic acid. The present invention also provides for a method of removing a sugar from a solution, comprising: (a) providing a solution comprising (i) an IL or ILA phase and (ii) an organic phase, wherein the solution comprises an IL, a sugar and a boronic acid; (b) contacting the sugar with the boronic acid to form a sugar-boronic acid complex, (c) separating the organic phase andmore » the aqueous phase, wherein the organic phase contains the sugar-boronic acid complex, and optionally (d) separating the sugar from the organic phase.« less
  • A variety of hypoglycemic agents and compositions for use in the maintenance of maturity onset non-insulin dependent diabetes mellitus (NIDDM) are disclosed. The present invention also discloses methods for reducing the blood glucose level in a patient, as well as methods for reducing symptomatic conditions associated with diabetes in a patient.
