Abstract: The present invention is generally concerned with the care of animals, particularly animals intended for human nutrition, for example animals used in farming and aquaculture, and is also particularly concerned with the care of pet animals. In this context, the invention relates to compositions, in particular feed compositions, veterinary formulations and antimicrobial compositions for the prevention, treatment and/or amelioration of infections by parasitic or pathogenic microorganisms. The invention also provides uses of such compositions, feeding regimes and methods for rearing or treating animals. The invention is also concerned with compositions and uses thereof for improving agronomic traits and animal health parameters.

Abstract: Process for modulation of a taste and/or aftertaste in foods, articles consumed for pleasure, animal feeds, sweeteners and cosmetics comprising at least one high intensity sweetener HIS by addition of a taste modulator comprising a salt preparation, and use of a salt preparation for taste modulation of foods, articles consumed for pleasure, animal feeds, sweeteners and cosmetics comprising at least one HIS.

Abstract: Process for modulation of a taste and/or aftertaste in foods, articles consumed for pleasure, animal feeds, sweeteners and cosmetics comprising at least one high intensity sweetener HIS by addition of a taste modulator comprising at least one polyoxyethylene sorbitan fatty acid ester which is suitable for food, and use of a at least one polyoxyethylene sorbitan fatty acid ester which is suitable for food for taste modulation of foods, articles consumed for pleasure, animal feeds, sweeteners and cosmetics comprising at least one HIS.

Abstract: Process for taste modulation of compositions of matter which comprise at least one High Intensity Sweetener HIS, which comprises adding at least two azo compounds in a total concentration of 0.1 to 30 ppm or 0.1 to 30 mg/l as taste modulators to a composition of matter which comprises at least one HIS.

Abstract: Use of at least one type of water-dispersible carotenoid nanoparticles as taste modulators in compositions of matter; process for taste modulation of compositions of matter in which at least one type of water-dispersible carotenoid nanoparticles is added to compositions of matter; and also taste modulators for compositions of matter comprising (A) at least one type of water-dispersible carotenoid nanoparticles and (B) at least one azo compound, comprising at least one azo group.

Abstract: The invention relates to a lipase variant which can be prepared by carrying out, on the amino acid sequence of a starting lipase selected from the lipase homologous family I.1 or I.2, at least one amino acid substitution in those positions which correspond to the positions 17, 29, 30, 52, 86, 117, 122, 160, 163, 167, 265, 266, 286, 289 in the prototype lipase sequence SEQ ID NO: 1.

Abstract: The invention relates to a method for producing carotenoids or their precursors using genetically modified organisms of the Blakeslea genus. Said method comprises the following steps (i) transformation of at least one of the cells, (ii) optional homokaryotic conversion of the cells obtained in step (i) to produce cells, in which one or more genetic characteristics of the nuclei are all modified in an identical manner and said modification manifests itself in the cells, (iii) selection and reproduction of the genetically modified cell or cells, (iv) cultivation of the genetically modified cells, (v) preparation of the carotenoids produced by the genetically modified cells or the carotenoid precursor produced by said genetically modified cells. The invention also relates to carotenoids or their precursors produced according to said method and to the use thereof.

Abstract: The present invention relates to a method for preparing a normalized gene library from nucleic acid extracts of soil samples and to gene structures and vectors used in said method. The invention further relates to the use of the normalized gene library for the screening of genes coding for novel biocatalysts from the soil samples.
