  • DNA encoding a protein having D-lactate dehydrogenase activity and uses thereof
    Patent number: 7964382
    Abstract: This invention provides a polynucleotide that encodes a protein having lactate dehydrogenase activity and such protein that can be used for producing D-lactic acid. This polynucleotide has the nucleotide sequence as shown in SEQ ID NO: 1 (a), and it hybridizes under stringent conditions with a probe comprising all or part of the nucleotide sequence as shown in SEQ ID NO: 1 or a complementary strand thereof and encodes a protein having D-lactate dehydrogenase activity (b).

  • Cell culture support and production method and uses thereof
    Publication number: 20100216242
    Abstract: The present teachings provide a practical cell culture support by which a cell culture with a high degree of freedom can be realized. More specifically, the cell culture support includes a polymer layer exhibiting thermoresponsiveness and a cell culture region obtained by plasma-treating a surface layer portion thereof with a reactive gas, whereby a cell culture support having thermoresponsiveness and cellular adhesiveness while avoiding or limiting the use of cell adhesion factors is provided.

  • METHOD FOR PRODUCING LACTIC ACID
    Publication number: 20090104675
    Abstract: Lactic acid with high optical purity that has not previously been achieved is produced. It has been found that the optical purity of lactic acid is reduced as the racemization reaction of lactic acid proceeds when lactic acid coexists with glycerol. By reducing the amount of glycerol prior to concentrating lactic acid by heating, the optical purity of lactic acid after concentration by heating can be maintained at a high level.
