Abstract:
The present invention relates to a method for production of cysteine or its derivatives using O-phosphoserine as an intermediate and recombinant microorganism for use in production of O-phosphoserine.
Abstract:
The present invention relates to Corynebacterium sp. that is transformed with an Escherichia sp.-derived fructokinase gene to express fructokinase showing a sufficient activity of converting fructose into fructose-6-phosphate, thereby preventing unnecessary energy consumption, and a method for producing L-amino acids using the strain. The transformed Corynebacterium sp. of the present invention is able to express fructokinase from the Escherichia -derived fructokinase gene to prevent unnecessary energy consumption during fructose metabolism, leading to more cost-effective production of L-amino acids. Therefore, it can be widely used for the effective production of L-amino acids.
Abstract:
The present invention relates to a microorganism of the genus Corynebacterium having an ability to produce L-arginine, and a method of producing L-arginine using the same.

Abstract:
The present invention relates to a microorganism of the genus Corynebacterium, which has an enhanced activity of aspartate ammonia-lyase and/or aspartate aminotransferase, and thus has an enhanced ability to produce L-arginine, and to a method of producing L-arginine using the microorganism of the genus Corynebacterium .
Abstract:
The present invention relates to a microorganism belonging to the genus Escherichia sp. and a method for producing L-amino acid using the same. The microorganism belonging to the genus Escherichia sp. with sucrose assimilability and L-amino acid producing ability is obtained by introducing a gene encoding a sucrose assimilative microorganism-derived sucrose metabolic enzyme to the sucrose non-assimilative microorganism belonging to the genus Escherichia sp. having an L-amino acid producing ability.
