Abstract: The invention relates to the use of a persistent, weatherable blend of a bird repellent and a paint coating composition on exterior surfaces such as wood or building materials, to deter birds from damaging such wood or building material. The bird repellent blend has improved weatherability while retaining the effectiveness of the bird repellent.

Abstract: Compositions and methods for inhibiting sulfide biogeneration from biofilms are described, as well as methods for preparing the compositions. The compositions comprise anthrahydroquinone and a biocide. The compositions may also include anthraquinone.

Abstract: The invention provides a biological method of producing isoprenoids.

Abstract: Compositions and methods for inhibiting sulfide biogeneration from biofilms are described, as well as methods for preparing the compositions. The compositions comprise anthrahydroquinone and a biocide. The compositions may also include anthraquinone.

Abstract: A biosynthetic method for producing glucosamine and N-acetylglucosamine is disclosed. Such a method includes the fermentation of a genetically modified microorganism to produce glucosamine and/or N-acetylglucosamine. Also disclosed are genetically modified microorganisms that are useful for producing glucosamine and N-acetylglucosamine. In addition, methods of recovering N-acetylglucosamine that has been produced by a fermentation process, including methods that result in N-acetylglucosamine of high purity, are described. Also disclosed is a method to produce glucosamine from N-acetylglucosamine.

Abstract: A food product and method for treating and preventing diarrhea in a subject animal suffering from or susceptible to diarrhea. The method comprises administering an egg product to the subject animal wherein the egg product is obtained from a hyperimmunized avian.

Abstract: A product and method for reducing and preventing the ingestion of substrates by avians wherein the substrates are disposed within an avian house. The product is a bird repellent in combination with a substrate disposed within an avian house. As a result of the reduced ingestion of substrates such as litter, healthier avians are achieved.

Abstract: A method for deterring birds from perching, roosting or loafing on plant and structural surfaces by applying to the surfaces a non-toxic composition. The non-toxic composition is one that triggers a physiological aversion mechanism in birds by a visual cue and a post-ingestinal response.

Abstract: The invention is an acid-chitosan complex which is made up of chitosan, a sufficient amount of one or more acids, and an effective amount of water. This acid-chitosan is water-soluble in a dry form. A further aspect of this invention is various methods for producing such a water-soluble acid-chitosan complex and methods for using this acid-chitosan complex, particularly for reducing fat absorption in an animal.

Abstract: A method for reducing the level of hydrogen sulfide in water containing sulfur-reducing bacteria and hydrogen sulfide-metabolizing bacteria by addition of an aqueous solution of metallic nitrogen oxides and small particles of water-insoluble polycyclic quinones.
