Abstract:
One embodiment of the present invention relates to a metabolism network model of Corynebacterium glutamicum for producing 1,4-BDO by Corynebacterium glutamicum, which is a strain that does not produce 1,4-BDO in a natural state. On the basis of the network model, metabolic properties of Corynebacterium glutamicum are analyzed. By predicting effects of a deletion target enzyme (ldhA, mqo or mdh) in a state in which Cat1, sucD, 4hbD, cat2 and adhE are included, and removing them, production efficiency of 1,4-BDO and increase of 1,4-BDO under the same fermentation conditions are confirmed. In addition, transformation microorganism produced by the method can produce 1,4-BDO in high efficiency, and therefore, can be effectively used in the industries.
Abstract:
PURPOSE: A modified microorganism with improved xylose utilization is provided to produce chemical materials. CONSTITUTION: A modified microorganism converts xylose into xylitol by xylose reductase, xylitol into xylulose by xylitol dehydrogenase, and xylulose into xylulose-5-phosphate by xylulokinase. The microorganism produces a chemical material using xylose. Xylose is converted into xylitol by xylose reductase. The xylose reductase and xylitol dehydrogenase activities are derived from Pichia stipitis. The xylulokinase activity is derived from Saccharomyces cerevisiae. The modified microorganism is E.coli or Kluyveromyces marxianus. The chemical material includes alcohol, organic acid, amino acid, or vitamin. The modified microorganism is deposited by deposit number KCTC11951BP, KCTC11952BP or KCTC11953BP.
Abstract:
PURPOSE: A recombinant microorganism which produces 3-hydroxypropionic acid(3-HP) using a malonic semialdehyde reduction pathway is provided to remarkably enhance 3-HP productivity by gene manipulation. CONSTITUTION: A recombinant microorganism for producing 3-hydroxypropionic acid has a pathway for sequentially producing pyruvate, acetyl Co, malonyl-CoA, and malonic semialdehyde. The microorganism includes Escherichia sp., Saccharomyces sp., or Kluyveromyces sp. A gene encoding lactate dehydrogenase is IdhA or a homolog or a variant thereof. A gene encoding phosphotransacetylase is pta or a homolog or a variant thereof.
Abstract:
PURPOSE: A modified microorganism for producing lactic acids and a method for producing lactic acids are provided to produce lactic acids with high efficiency under an acidic condition. CONSTITUTION: A modified microorganism for producing lactic acids with high efficiency has LDH activity of Pelodiscus sinensis japonicus, Ornithorhynchus anatinus, Tursiops truncates, and Rattus norvegicus. The modified microorganism is yeast or bacteria. The modified microorganism is E.coli or Kluyveromyces marxianus. The modified microorganism produces lactic acids with 12.2% or more of glucose. An expression vector for producing the modified microorganism comprises: a replication origin; a promoter; a polynucleotide; and a terminator. A method for producing lactic acids comprises: a step of culturing the modified microorganism in a medium containing glucose; and a step of collecting lactic acids from the culture.

PURPOSE: A modified microorganism for producing lactic acids is provided to prepare lactic acids with high efficiency under an acidic condition. CONSTITUTION: A modified microorganism for producing lactic acids has a lactate dehydrogenase(LDH) activity of Pelodiscus sinensis japonicus, Ornithorhynchus anatinus, Tursiops truncates, or Rattus norvegicus. The modified microorganism is Escherichia sp. or Kluyveromyces sp. The modified microorganism produces lactic acids with 34% or more of glucose. An expression vector contains: a replication origin for constructing the modified microroganisms; a promoter; a polynucleotide coding LDH activation of one or more species selected from the group consisting of Pelodiscus sinensis japonicus, Ornithorhynchus anatinus, Tursiops truncates, or Rattus norvegicus; and a terminator. The replication origin is ARS/CEN replication origin.
