    摘要: The present invention relates to a polypeptide capable of increasing the production of L-methionine in a microorganism. In particular, the present invention relates to an YgaZ and YgaH polypeptide or a complex thereof, referred to herein as YgaZH polypeptide, which are novel putative L-methionine exporters, polynucleotides encoding the same, a recombinant vector comprising the polynucleotide, a microorganism transformed with the recombinant vector, and a method for producing L-methionine and/or S-adenosyl-methionine, comprising the steps of culturing the transformed microorganism to produce L-methionine and/or S-adenosyl-methionine, and isolating L-methionine and/or S-adenosyl-methionine. The transformed microorganism of the present invention produces L-methionine in a high yield, thereby being used for medicinal and pharmaceutical industries and feed industry, in particular, animal feeds

    摘要: A method for producing L-threonine using a microorganism is provided. In the method, the threonine dehydratase (tdc) gene existing in the genomic DNA of the microorganism is partially deactivated using a recombination technique. For a microorganism strain with enhanced activity of threonine operon-containing enzymes and the phosphoenolpyruvate carboxylase (ppc) gene, the tdc gene engaged in one of the four threonine metabolic pathways is specifically deactivated, thereby markedly increasing the yield of L-threonine.

    摘要: A method of isolating 1,3-propanediol from a solution containing 1,3-propanediol, 1,2-propanediol, glycerol, and glucose is provided. The method includes: obtaining a concentrate by concentrating the solution via reduced pressure evaporation; dissolving the concentrate in a solvent selected from the group consisting of ethyl acetate, methyl ethyl ketone, and a mixture thereof and leaving the solution alone to fractionate the compounds in a solvent layer and a water layer; and loading the solvent layer in a silica-filled column under a low pressure liquid chromatography condition and eluting the solvent layer with a mixed solvent of methanol and at least one solvent which is miscible with methanol and has a polarity lower than methanol.
