  • Patent number: 8889921
    Abstract: Methods of synthesis of scyllitol diborate and related compounds are provided, including methods that are performed in all-aqueous solutions. Also provided are methods in which the reaction products are recycled to increase the efficiency of the process. The methods include the steps of conversion of a solution of inositol to scyllitol, conversion of scyllitol in the solution to scyllitol diborate, and isolation of the scyllitol diborate from the solution. The scyllitol diborate is reacted to form substantially pure scyllitol diborate, and the remaining solution is efficiently recycled to scyllitol diborate, then to additional substantially pure scyllitol. This scyllitol diborate recycling step can be applied to a variety of processes to improve the yield of scyllitol. The methods are highly efficient and result in large scale reaction products of high purity.

  • Publication number: 20140322775
    Abstract: It is intended to provide a novel NAD+-independent myo-inositol 2-dehydrogenase which converts myo-inositol into scyllo-inosose in the absence of NAD+; a novel enzyme scyllo-inositol dehydrogenase which stereospecifically reduces scyllo-inosose into scyllo-inositol in the presence of NADH or NADPH; and a novel microorganism which belongs to the genus Acetobacter or Burkholderia and can convert myo-inositol into scyllo-inositol. By using these enzymes or the microorganism, scyllo-inositol is produced. Furthermore, scyllo-inositol is purified by adding boric acid and a metal salt to a liquid mixture containing scyllo-inositol and a neutral saccharide other than scyllo-inositol to form a scyllo-inositol/boric acid complex, separating the complex from the liquid mixture, dissolving the thus separated complex in an acid to give an acidic solution or an acidic suspension and then purifying scyllo-inositol from the acidic solution or the acidic suspension.

    Abstract: A method of preparing a modified corn steep liquor product from a corn steep liquor which includes suspended solids, high molecular weight compounds, phytic acid, and metal values includes the steps of: subjecting the corn steep liquor to ultrafiltration to remove the suspended solids and high molecular weight compounds; treating the product of step (a) with a phytase enzyme to convert the phytic acid to inositol-mono-phosphate; treating the product of step (b) with an acid phosphatase enzyme to convert the inositol-mono-phosphate to myo-inositol; adjusting the pH of the product of step (c) to from 7 to 9 inclusive using a soluble base which causes most or all of the Mg values to precipitate, and removing the precipitate; and contacting the product of step (d) with a strong acid cation chromatographic resin to produce a first fraction containing most of the remaining metal values and a second fraction containing most of the myo-inositol, the second fraction being the modified corn steep liquor product.

  • Patent number: 6645767
    Abstract: Methods and materials are provided for stably introducing any gene into a specific locus in the genome of a microorganism such as yeast without the addition of any drug resistance genes. Specifically provided herein are new genetically engineered inositol-overproducing Saccharomyces cerevisiae strains obtained by using a novel set of yeast integration plasmids that allow the safe, stable, and controlled introduction of homologous as well as heterologous genes into the host genome. In particular, specific loci of the S. cerevisiae yeast genome can be targeted with single or multiple copies of a specific gene that is desired to be expressed or a given set of specific genes that the host can use without the addition of any drug resistance genes. The principles of this new methodology can also be used for the construction of other recombinant yeast and bacterial strains as well as higher eukaryotic cells.

  • Publication number: 20030120121
    Abstract: A reactant selected from the group consisting of alkanes, alkenes, and aromatics is reacted with a metal halide to form the halide of the reactant and reduced metal. The reduced metal is oxidized to form metal oxide. The metal oxide is reacted with the halide of the reactant to produce the alcohol and/or the ether corresponding to the reactant and the original metal halide which is recycled.
