  • Patent number: 8278438
    Abstract: The production of a diutan polysaccharide exhibiting increased viscosity properties as compared with previously produced polysaccharide of the same type of repeating units. Such an improved diutan polysaccharide is produced through the generation of a derivative of Sphingomonas sp. ATCC 53159 that harbors a multicopy broad-host-range plasmid into which genes for biosynthesis of diutan polysaccharide have been cloned. The plasmid provides the capability within the host Sphingomonas strain to produce multiple copies of genes for such polysaccharide synthesis. In such a manner, a method of not just increased production of the target diutan polysaccharide, but also production of a diutan polysaccharide of improved physical properties (of the aforementioned higher viscosity) thereof is provided. Such a diutan polysaccharide has proven particularly useful as a possible viscosifier in oilfield applications and within cement materials.

  • Patent number: 8273873
    Abstract: A sucrose of a conformational polymorph and its manufacturing method are disclosed. The sucrose is a Form II sucrose having a melting point of 140-180° C., and furfuryl alcohol is added into a saturated sucrose solution by a reverse solution method, such that the saturated solution is recrystallized to form a new sucrose. The sucrose of this conformational polymorph has a melting point lower than the melting point of a general Form I sucrose, and the solubility of the Form II sucrose is different from the solubility of the Form I sucrose. Thus the Form II sucrose can be used as an excipient of medicines, sacrificial fiber blood vessel network structure for cell cultivations, or the manufacture of an optical interference wavy device. Since the hydrogen bonds in the molecular structure of the Form II sucrose and the Form I sucrose are different, the mechanoluminescence of the sucrose is affected.

  • Patent number: 8168778
    Abstract: An object of the present invention is to provide a novel starchy substance having a retrogradation-resistance, a process for producing the starchy substance efficiently from a material starch by enzymatic reaction, and uses thereof. The present invention attains the above object by providing branched starch having 6-?-maltosyl- and/or 6-?-maltotetraosyl-structure(s) with a marked retrogradation-resistance, a process for producing the branched starch without lowering the molecular weight of material starch, and uses thereof.

  • Patent number: 8158608
    Abstract: Ulcer is a serious oxidative stress induced disease with complex pathologic events including upregulation of H+K+ ATPase of parietal cell (PC) membrane, damage of mucin layer around PC, PC-DNA damage etc. The polysaccharide (GRPP) fraction and antioxidant extract (GRAOX) of ginger was examined for their ability to inhibit H+ K+ ATPase. Results indicated that the inhibition of H+ K+ ATPase activity which causes acidity in the lumen of the stomach, also exhibited better H+K+ ATPase inhibition (PPI) at the IC50 of 27.2 ?g (GRPP) and 16.5 ?g GAE (AOX) respectively than the known antiulcer proton pump blocker Lansoprazole (19.3 ?g). Further the antioxidant activity in antioxidant extract (GRAOX) by various assay systems was examined such as Reducing power, Free radical scavenging (FRS), DNA and cytoprotection systems etc. GRAOX exhibited concentration dependent reducing power ability at 5-25 ?g equivalent of phenol. FRS activity with IC50 of 6.8 ?g equivalent of phenol etc. At 0.

  • Patent number: 8158778
    Abstract: The present invention provides the means for suppressing the production of decomposition reactant, isomerization reactant, colored material, and so on when a saccharide solution is desalted, thereby suppressing the production of impurities and preventing coloration of an ion exchange resin and decrease in the desalting capacity of the ion exchange resin. The desalting of a saccharide solution is performed by using an anion exchange resin supporting a carbonate ion and/or a hydrogencarbonate ion.

  • Patent number: 8153782
    Abstract: Processes for recycling an ionic liquid comprising employing an initial ionic liquid as a solvent and/or reagent resulting in a modified ionic liquid and thereafter subjecting at least a portion of the modified ionic liquid to at least one anion exchange process to produce a reformed ionic liquid. The initial ionic liquid can be employed in a cellulose esterification process, thereby producing the modified ionic liquid. At least a portion of the reformed ionic liquid can be recycled to a point upstream in the cellulose esterification process.
