  • Method for producing 3-hydroxy nitrogen-containing six-membered cylic compound
    Patent number: 5763232
    Abstract: A method for producing a 3-hydroxy nitrogen-containing six-membered cyclic compound is provided. Namely, microbial cells of a microorganism and/or a preparation obtained from the microbial cells is allowed to act on a nicotinic acid derivative or a 2-pyrazinecarboxylic acid derivative represented by the following general formula: ##STR1## wherein R.sub.1 and R.sub.2 may be the same or different, representing hydrogen atom, halogen atom, hydroxyl group, amino group, carboxyl group, cyano group, oxime group, or alkyl group having a number of carbon atom or atoms of 1 to 5 respectively, and A represents carbon atom or nitrogen atom, the microbial cells and/or the preparation obtained from the microbial cells having an ability to perform hydroxylation of the nicotinic acid derivative or the 2-pyrazinecarboxylic acid derivative accompanied by decarboxylation of carboxyl group.

  • Method of manufacturing inulotriose and/or inulotetrose using an exo-type hydrolase capable of hydrolyzing a fructan only every 3 or 4 sugar units from a terminal fructose
    Patent number: 5122460
    Abstract: The present invention is directed to a method of manufacturing inulotriose and/or inulotetrose by using an exo-type hydrolase capable of hydrolyzing a fructan only every 3 or 4 sugar units from a terminal fructose thereof, so as to produce inulotriose and/or inulotetrose, and of recovering the inulotriose and/or inulotetrose. The enzyme is produced by Streptomyces sp. MCI 2423 (FERM BP-2678) and Aureobacterium sp. MCI 2494 (FERM BP-2679).

  • Exo-type hydrolase capable of hydrolyzing a fructan only every 3 or 4 sugar units
    Patent number: 5089402
    Abstract: The present invention is directed to an exo-type hydrolase capable of hydrolyzing a fructan only every 3 or 4 sugar units from a terminal fructose thereof to produce predominantly inulotriose and/or inulotetrose. The enzyme is produced by Streptomyces sp. MCI 2423 (FERM BP-2678) and Aureobacterium sp. MCI 2494 (FERM BP-2679).
