  • Patent number: 6709763
    Abstract: Articles produced from hydrophobic polymers (e.g., polyethylene) are surface-coated with thin films of starch in order to render the surfaces hydrophilic. The thin coatings form on the surfaces of plastic objects when the objects are placed in contact with hot, aqueous solutions of starch. These starch coatings are extremely adherent to the hydrophobic plastic surfaces under both wet and dry conditions, and they permit the surfaces to be uniformly wet with water. Resultant products have improved biocompatibility, improved compatibility with hydrophilic reagents, reduced build-up of electrostatic charge, reduced blocking, reduced friction, improved absorption of water-based dyes, and improved adhesion properties. The starch coatings are non-toxic, inexpensive and biodegradable.

  • Patent number: 6660291
    Abstract: The entomopathogenic fungus Paecilomyces fumosoroseus and certain related species, such as P. javanicus are useful for controlling infestations by subterranean termites, particularly those belonging to the family Rhinotermitidae. The family Rhinotermitidae includes two species of subterranean termites having extremely high economic importance in the United States; namely the Formosan subterranean termite (Coptotermes formosanus Shiraki), and the native (North American) subterranean termite (Reticulitermes flavipes). Large numbers of infectious propagules of the fungus, such as blastospores and conidia can be readily cultured on media that are easily and inexpensively prepared and incorporated into formulations for controlling termites. These fungi are useful for protecting living trees, plants, wood, wood structures, and other cellulosic materials susceptible to termite infestation and damage.

  • Patent number: 6639132
    Abstract: Improved corn lines having high protein and/or oil content and a method for producing such a lines. In another embodiment, improved corn lines having high oleic fatty-acid content, and/or either elevated or lowered saturated fat content, and a method for producing such a lines. In yet another embodiment, improved corn lines having a starch composition including starch components having a lower peak onset, having lower or higher enthalpy of gelatinization (cal/g), having lower or higher range of gelatinization (° C.), and/or having lower or higher percentage retrogradation. According to the present invention, new genes are introduced from a novel source, viz. Tripsacum dactyloides L., into the Corn-Belt genome or other conventional corn lines and thus the genetic diversity is increased and germplasm and value-added trait enhancement are allowed through traditional plant breeding practices. Introgression merges Tripsacum genetic material into the corn breeding stock.

  • Patent number: 6461999
    Abstract: Lubricating additives for drilling fluids are prepared from semi-solid highly viscous and/or high molecular weight lubricants, such as polyalkylenes (e.g., polybutene), by steam jet cooking a mixture of starch, water, and the lubricant in order to uniformly suspend micrometer-sized lubricant droplets in an aqueous starch matrix. These additives avoid the need for toxic emulsifiers, surfactants, or short-chain hydrocarbon solvents for dispersing the lubricants. They impart lubricity to drilling fluids (muds) and also inhibit fluid loss in geological formations by enhancing the filtration control properties of the fluid.

  • Patent number: 6379726
    Abstract: An edible, water-resistant composition that can be formed into shaped articles including film comprises a water-resistant solid composition of casein. The casein composition may be directly precipitated from a solution under high pressure treatment with carbon dioxide. The composition does not have to be crosslinked, but takes advantage of the natural water-insolubility of the protein backbone of the casein. The casein composition may be combined with edible or inert flexibilizers to improve film properties, and the film may be used to protect food products or food compositions, yet provide moisture protection. The film of casein material may exhibit water-insolubility in deionized water at 20° C. of less than 25% by weight after two hours of immersion of the film in the deionized water, with or without mild agitation.
