    摘要: Flavine nucleotides, which are useful as ingredients of nutrient compositions, raw materials for various pharmaceutical products, biochemical research reagents and so on, are produced from flavine nucleotide precursors and ATP by utilizing cells or a culture of a microorganism which belongs to the genus Escherichia, Enterobactor or Pseudomonas and harbors a recombinant DNA comprising a vector DNA and a DNA fragment carrying the genetic information relevant to the synthesis of FMN and/or FAD, or treated cells or a treated culture of the microorganism.

    摘要: The present invention provides a polymer comprising a polysaccharide having excellent water absorption properties, moisture absorption properties, moisture retention properties and thickening properties. Said polysaccharide has the following properties: (A) the principal constituents of the sugar composition are rhamnose, fucose, glucose and glucuronic acid which are present in a molar ratio of (1-4):2:(1-8):(1-4); (B) elemental analysis (wt %):C: 36 .+-.3H: 7 .+-.1O: 56 .+-.4,containing 9-13% of crystalline water(C) solubility:slightly soluble in water; soluble in alkalies; insoluble in methanol, ethanol and acetone;(D) UV absorption spectrum:no absorption detected at 280 nm characteristic of proteins (peptides) or at 260 nm characteristic of nucleic acids; and(E) IR absorption spectrum:an absorption pattern characteristic of polysaccharides is observed near 800-1200.sup.-iSaid polysaccharide is produced by a fermentation method using a natural medium or a synthetic medium of Alcaligenes microorganism.
