    摘要: Healthcare costs are a significant worldwide, with many patients being denied medications because of their high prices. One approach to addressing this problem involves the biosynthesis of chiral drug intermediates, an environmentally friendly solution that can be used to generate pharmaceuticals at much lower costs than conventional techniques. In this context, embodiments of the invention comprise methods and materials designed to allow microorganisms to biosynthesize the nonnatural amino acid L-homoalanine. As is known in the art, L-homoalanine is a chiral precursor of a variety of pharmaceutically valuable compounds including the anticonvulsant medications levetiracetam (sold under the trade name Keppra®) and brivaracetam, as well as ethambutol, a bacteriostatic antimycobacterial drug used to treat tuberculosis. Consequently, embodiments of the invention can be used in low cost, environmentally friendly processes to generate these and other valuable compounds.

    摘要: The disclosure provides a process that converts CO2 to higher alcohols (e.g. isobutanol) using electricity as the energy source. This process stores electricity (e.g. from solar energy, nuclear energy, and the like) in liquid fuels that can be used as high octane number gasoline substitutes. Instead of deriving reducing power from photosynthesis, this process derives reducing power from electrically generated mediators, either H2 or formate. H2 can be derived from electrolysis of water. Formate can be generated by electrochemical reduction of CO2. After delivering the reducing power in the cell, formate becomes CO2 and recycles back. Therefore, the biological CO2 fixation process can occur in the dark.

    摘要: Disclosed herein is a method for producing monohydric alcohols from monocarboxylic acids or derivatives thereof using a catalyst comprising ruthenium (Ru) and tin (Sn) using zinc oxide (ZnO) as both a catalyst support and an active promoter; a catalyst prepared by adding an inorganic binder such as silica, alumina or titania in a limited range to the catalyst comprising the above components in order to impart a shaping ability to the catalyst; or, a modified catalyst reformed by adding at least one reducing component selected from the group consisting of Co, Ni, Cu, Ag, Rh, Pd, Re, Ir, and Pt to the catalyst in order to improve the reducing ability of the catalyst. By using such catalysts, the method according to the present invention is advantageous in that the monohydric alcohols can be prepared in high yield regardless of whether the monocarboxylic acids contain water or not, the monohydric alcohols can be economically prepared because the catalysts can be operated under mild reaction conditions and also exhibits high selectivity and productivity compared to conventional catalysts, and the catalysts have excellent long-term reaction stability so as to be advantageous for industrial applications.
