摘要:
Novel plant proteins (SAFPs) which synergize the activity of antifungal antibiotics are identified. SAFPs are demonstrated to synergize antifungal antibiotics, such as nikkomycins, polyoxins and amphotericins. SAFPs alone also display antifungal activity against several species of fungi, including strains of Candida, Trichoderma, Neurospora and strains of the plant pathogens Fusarium, Rhizoctonia, and Chaetomium. Synergistic antifungal compositions containing SAFP and antifungal antibiotics are provided. In particular, synergistic compositions of corn-SAFP (zeamatin), sorghum-SAFP (sormatin) or oat-SAFP (avematin) and nikkomycin are found to be effective as antifungal compositions, especially against the opportunistic human pathogen Candida albicans. Method for employing SAFPs and synergistic compositions containing them for the inhibition of fungi are provided. In addition, a method for purifying SAFP from grain meal is provided.

摘要:
Heat-stable, red pigment compositions comprising a physical mixture of 1,4-diketo-3,6-di(4-biphenylyl)-pyrrolo [3,4 c]-pyrrole and a 2,9-dichloroquinacridone pigments, processes for preparing the pigment compositions and the use of the compositions for pigmenting high-molecular-weight organic materials are disclosed.
摘要:
Plastic mixtures, in particular recycled plastic mixtures, comprising predominantly polyolefins and 0.05-20 % by weight of PVDC can be stabilized against thermo-oxidative degradation by addition of a combination of an organic phosphite or phosphonite and a metal salt of a fatty acid.
摘要:
A process is described for flame-proofing organic polymeric materials by means of a low temperature plasma treatment in the presence of at least one volatile, low-molecular compound. The process comprises subjecting a volatile compound, selected from a halogen-free phosphorus compound, to the low temperature plasma, such that a homogeneous polymeric structure forms on the organic material. A very wide range of organic materials can be effectively flame-proofed with the process of this invention without adversely affecting their other properties such as mechanical properties or photochemical stability.
摘要:
New cytochrome P-450 dependent monooxygenases and DNA molecules encoding these monooxygenases are provided, which are able to catalyze the biosynthetic pathway from amino acids to their corresponding cyanohydrins, the precursors of the cyanogenic glycosides, or to glucosinolates. 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.
