摘要： The present in provides for novel metabolic pathways leading to propanol, alcohol or polyol formation in a consolidated bioprocessing system (CBP), where lignocellulosic biomass is efficiently converted to such products. More specifically, the invention provides for a recombinant microorganism, where the microorganism expresses one or more native and/or heterologous enzymes; where the one or more enzymes function in one or more engineered metabolic pathways to achieve: (1) conversion of a carbohydrate source to 1,2-propanediol, isopropropanol, ethanol and/or glycerol; (2) conversion of a carbohydrate source to n-propanol and isopropanol; (3) conversion of a carbohydrate source to isopropanol and methanol; or (4) conversion of a carbohydrate source to propanediol and acetone; wherein the one or more native and/or heterologous enzymes is activated, upregulated or downregulated.

摘要： The present invention provides non-petroleum high-octane fuel which may be derived from biomass sources, and a method of producing same. The method of production involves reducing the biomass feedstocks to sugars, fermenting the sugars using microorganisms or mutagens thereof to produce ethanol or acetic acid, converting the acetic acid or ethanol to acetone, and converting the acetone to mesitylene and isopentane, the major components of the engine fuel. Trimerization of acetone can be carried out in the presence of a catalyst containing at least one metal selected from the group consisting of niobium, iron and manganese. The ethanol can be converted to mesitylene in a dehydration reaction in the presence of a catalyst of zinc oxide/calcium oxide, and unreacted ethanol and water separated from mesitylene by distillation. These ethanol-based fuels may be formulated to have a wide range of octane values and energy, and may effectively be used to replace 100 LL aviation fuel (known as AvGas), as well as high-octane, rocket, diesel, turbine engine fuels, as well as two-cycle, spark-ignited engine fuels.
