Alternatively, the oligosaccharide composition can be produced by a process that comprises heating an aqueous feed composition that comprises at least one monosaccharide or linear saccharide oligomer, and that has a solids concentration of at least about 70% by weight, to a temperature of at least about 40° C.Type: GrantFiled: September 15, 2006Date of Patent: November 15, 2011Assignee: Tate & Lyle Ingredients Americas LLCInventors: Michael D.

Patent number: 8022269Abstract: The present invention relates to methods for increasing the yield of a compound produced by an organism. More particularly, the present invention relates to methods for increasing the total or soluble carbohydrate content or sweetness or increasing the content of an endogenous carbohydrate of a plant tissue by producing a sugar-metabolizing enzyme that catalyzes the conversion of an endogenous sugar (one that is normally produced in the plant) to an alien sugar (one that is not normally produced in the plant at the same developmental stage). The invention also relates to plants and plant parts that produce a sugar-metabolizing enzyme to yield an alien sugar, with the consequence of higher total fermentable carbohydrate content, and to fermentable carbohydrates and other products derived therefrom.Type: GrantFiled: October 11, 2006Date of Patent: September 20, 2011Assignee: The University of QueenslandInventors: Robert George Birch, Luguang Wu

Patent number: 8017828Abstract: To provide an agricultural chemical and the like with the use of an effect of inducing systemic acquired resistance in a plant. To provide a growth inhibitor of not only a plant pathogenic bacterium but also a harmful microorganism. Utilization of a rare sugar for inducing systemic acquired resistance in a plant or inhibiting the growth of a microorganism. Utilization thereof as an agricultural chemical with the use of the effect of inducing systemic acquired resistance in a plant, a plant disease inhibitor, an inducer of a plant growth regulatory factor (i.e., an inducer of plant hormone-like actions consisting of disease resistance, insect resistance, fruit maturation, breaking of dormancy, regulation of germination, drying resistance, and other than this, resistance to environmental stresses such as low temperature resistance, high temperature resistance, salt resistance and heavy metal resistance and promotion of flowering) and a microorganism growth inhibitor.Type: GrantFiled: May 24, 2005Date of Patent: September 13, 2011Assignees: Shikoku Research Institute Incorporated, National University Corporation Kagawa UniversityInventors: Ken Izumori, Kazuya Akimitsu, Shigeyuki Tajima, Mika Agarie, Tomohiro Yanagi, Ryosuke Mochioka
