The present invention relates to a microorganism belonging to the genussp. and a method for producing L-amino acid using the same. The microorganism belonging to the genussp. has a sucrose assimilability and L-amino acid producing ability, which is obtained by introducing a gene encoding a sucrose assimilative microorganism-derived sucrose metabolic enzyme to sucrose non-assimilative microorganism belonging to the genussp. having an L-amino acid producing ability and sucrose PTS (phosphoenolpyruvate dependent sucrose phosphotransferase system) activity.

Microorganism which produces L-amino acid and method for producing L-amino acid using the same

Disclosed is a polynucleotide encoding &#x3b3;-butyrobetaine hydroxylate (&#x3b3;-BBH) originating from. Also disclosed are a recombinant vector comprising the polynucleotide, a transformant transformed with the recombinant vector, &#x3b3;-BBH encoded by the polynucleotide, and a method of preparing L-carnitine, which comprises hydroxylating &#x3b3;-butyrobetaine using &#x3b3;-BBH encoded by the polynucleotide.

The present invention relates to a transformed microorganism producing an L-amino acid using sucrose as a main carbon source, and a method for producing an L-amino acid using the same.

Microorganisms for producing L-amino acids and process for producing L-amino acids using them

An L-threonine-producingin which a promoter of a phosphoenolpyruvate carboxylase (ppc) gene on the chromosome is substituted with a promoter of a cysteine synthase (cysK) gene and a method of producing L-threonine by using the same are disclosed. The recombinantmay produce L-threonine in a high yield, and thus may be widely used in medical, pharmaceutical, and feed industries, particularly for an animal feed.
