Abstract: The present invention relates to a microorganism producing L-methionine precursor, O-acetylhomoserine, and a method of producing L-methionine precursor using the microorganism.

Abstract: The present invention relates to a microorganism producing L-methionine precursor, O-succinylhomoserine, and a method of producing L-methionine precursor using the microorganism,

Abstract: The present invention relates to a method for producing L-methionine and organic acid comprising the following steps: Step 1) preparing a strain producing L-methionine precursor and producing L-methionine precursor by the fermentation of the strain; Step 2) producing L-methionine and organic acid by the enzyme reaction process with the L-methionine precursor as a substrate, and microorganism strains used in each step.

Abstract: 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.

Abstract: Provided are a polypeptide having glycerol-3-phosphate dehydrogenase activity and a 80% or more homology to an amino acid sequence as set forth in SEQ ID NO: 1 and a polypeptide having glycerol-3-phosphate phosphatase activity and a 80% or more homology to an amino acid sequence as set forth in SEQ ID NO: 2. Provided is also a method for producing glycerol, which includes: culturing a host cell transformed with a vector containing a polynucleotide including a first polynucleotide encoding an amino acid sequence as set forth in SEQ ID NO: 1 and a second polynucleotide encoding an amino acid sequence as set forth in SEQ ID NO: 2 which are operably linked to a suitable regulatory sequence; and recovering glycerol from the culture.

Abstract: A method of producing 1,2-propandiol is provided. The method includes incubating Klebsiella pneumoniae in a medium containing 10–30 g/L of a sugar carbon source excluding 6-deoxyhexose, in aerobic conditions; and separating 1,2-propandiol from the cultures. Using the method, 1,2-propandiol can be produced with a high yield by incubating Klebsiella pneumoniae in a medium containing a cheaper sugar carbon source.
