  • Patent number: 8530205
    Abstract: The present invention relates to a buffer composition for promoting production of calcitriol or calcifediol, and a method for producing calcitriol or calcifediol using the same. More particularly, the present invention relates to a buffer composition for promoting production of calcitriol or calcifediol comprising a metallic compound, an organic solvent, cyclodextrin, tris(hydroxymethyl)aminomethane, sodium succinate, sodium chloride, magnesium chloride, and water, and a method for producing calcitriol or calcifediol using the same. In the method for producing calcitiriol or calcifediol, the production yield of calcitriol or calcifediol is high, and the bioconversion is carried out in an enzyme reaction system instead of in a microorganism culture system. Thus, it is not required to maintain a sterile state. Also, the separation/purification following the completion of a biocatalytic reaction can be carried out in a cleaner state than the microorganism culture method.

  • Publication number: 20120232261
    Abstract: The present invention relates to a method for preparing low molecular weight hyaluronic acid from high molecular weight hyaluronic acid which is produced by Streptococcus sp. ID9102 (KCTC11395BP). The method of the invention for lowering a molecular weight of high molecular hyaluronic acid has a convenient process without the inconvenience of reprocessing for the removal of input materials, or requiring pH treatment, various reaction catalysts, and complicated additional treatment conditions as in a conventional method. The inventive method for lowering the molecular weight has an advantage in that according to a change of a reaction condition using activated carbon, the molecular weight of low molecular weight hyaluronic acid can be variously adjusted. The low molecular weight hyaluronic acid produced by the method of the invention can be produced in accordance with the standards of cosmetics or foods as well as medical supplies.
