  • Patent number: 6630338
    Abstract: An enzyme in a mixture containing the enzyme and a contaminant enzyme is purified by selectively aggregating and precipitating the contaminant enzyme with a surfactant. A deacetylase contaminant is separated from Cephalosporin C acylase using a cationic surfactant in an amount of 0.1 to 0.6%. Surfactants include benzylated or methylated cationic surfactants such as alkyl(palm)dimethylbenzyl ammonium chloride, alkyl(palm)trimethyl ammonium chloride and dodecyltrimethyl ammonium chloride. An immobilized enzyme is regenerated using a protease to remove the enzyme from a carrier. The carrier may be a synthetic adsorbent or an ion exchange resin having pores of 100 nm or less in diameter, and the immobilized enzyme is optionally crosslinked. Immobilized cephalosporin C acylase is regenerated using an alkaline or acidic protease.

  • Publication number: 20030129227
    Abstract: This invention provides &bgr;-lactam antibiotic-containing tablets capable of being orally taken either as such owing to their being small-sized, hence still easily swallowable, or, in the case of administration to the aged encountering some difficulty in swallowing, in the form of dispersions resulting from easy self-disintegration upon being dropped into water in a glass as well as a method of producing the same. The tablets of this invention comprise, on the per-tablet basis, 60-85% by weight of a &bgr;-lactam antibiotic, 1-10% by weight of low-substituted hydroxypropylcellulose and/or crosslinked polyvinylpyrrolidone as a disintegrator, and 0.5-2% by weight of a binder. Granules to be compressed for tableting are prepared using water or an aqueous solution of ethanol or the like.
