  • Laminates of acid polysaccharide films
    Patent number: 7935647
    Abstract: The present invention relates to a laminate prepared in part from a continuous acid polysaccharide film. In various embodiments, the laminate is useful for fabrication as a protective article as it typically is largely impermeable to hazardous chemical and biological agents, but is sufficiently permeable to water vapor that, if worn as protective apparel, it is both protective and comfortable to wear.
    Type: Grant

  • Cytochrome P450 monooxygenases
    Publication number: 20030041346
    Abstract: Cytochrome P450II dependent monooxygenases and DNA molecules encoding these monooxygenases are provided, which are able to catalyze the biosynthethic conversion of aldoximes to nitrils and the conversion of said nitrils to the corresponding cyanohydrins, which are the presursors of cyanogenic glycosides. Moreover, the invention provides methods for obtaining DNA molecules according to the invention and methods for obtaining transgenic plants resistant to insects, acarids, or nematodes or plants with improved nutritive value.
