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: 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: The invention provides methods of deacetylating N-acetylglucosamine by solid acid hydrolysis on a cation exchange resin. These methods advantageously reduce the amount of acid used and the need for acid recycle facilities. The isolated glucosamine salt produced is very clean, reducing or eliminating the need for further purification steps to decolorize or desalt the product. Using these methods, the number of crystallization steps required are minimized and the degradation of the N-acetylglucosamine in solution is significantly reduced leading to increased yield of high quality glucosamine.

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.
