  • Patent number: 7459294
    Abstract: During the production of a product compound by fermentation, the concentration of a precursor compound is maintained within a pre-selected concentration range by having an adsorbent resin in contact with the culture medium. The adsorbent resin reversibly adsorbs precursor compound and, as un-adsorbed precursor compound is converted to product compound, adsorbed precursor compound is released from the resin, thus maintaining the concentration of precursor compound within the pre-selected range.

  • Patent number: 7439045
    Abstract: An improved fermentation process for preparing pseudomonic acid A (mupirocin) is disclosed. The metabolically controlled fermentation process provides culturing a Pseudomonas sp. strain in a submerged medium at a temperature within about 20-30° C. The pH of the fermentation medium is regulated to be at about 5.5-6.0 by feeding the fermentation medium with an assimilable carbon source, a mineral salt, or an acidic/alkali solution. Accordingly, the resulting fermentation broth contains an increased yield of highly purified pseudomonic acid A as the main component. The pseudomonic acid B as an impurity in the fermentation broth is significantly decreased.

FKA-25 belonging to genus Pseudobotrytis sp. and having ability to produce FKA-25 substance in a medium, accumulating FKA-25 substance in the cultured medium, and collecting FKA-25 substance from the cultured mass. The obtained FKA-25 substance specifically inhibits the formation of the foam macrophage originated from mouse and is expected to be useful for prevention and treatment of arteriosclerosis and causative diseases therefrom.

  • Publication number: 20040185540
    Abstract: A chemoenzymatic process for the stereoselective preparation of both the (R) and (S) enantiomers of 3-hydroxy-3-(2-thienyl) propanenitrile has been developed. These optically pure key intermediates were prepared by enzymatic resolution of (+)3-hydroxy-3-(2-thienyl) propanenitrile both by transesterification and by hydrolysis reaction which were then transformed to both enantiomers of duloxetine.
