Abstract: The present invention provides genes encoding variants of metallo-endopeptidases that have been engineered to be resistant to prolonged boiling while having maintained their enzymatic performance at much lower temperatures. In addition, thermal stability of the metallo-endopeptidases is highly dependent on calcium at concentrations in the mM range. The invention further provides active metallo-endopeptidases variants whose stability depending on calcium concentration can be changed so as to provide metallo-endopeptidases that are calcium dependent or independent. The invention also provides genes that encode boiling-resistant metallo-endopetidases whose stability depending on calcium concentration can be changed. The invention also provides vectors and cells comprising these genes and proteases produced through these genes, vectors and/or cells.

Abstract: Described is a process and electronic data processing software program for carrying out same, for the creation of a flavor or fragrance formulation or for the determination of the use of a fragrance or flavor ingredient in a fragrance or flavor formulation or use thereof in or on a perfume composition, perfumed article, cologne, foodstuff, beverage, oral care product (e.g., mouthwash) and/or chewing gum.

Abstract: Described is apparatus and a process for collecting for subsequent analysis a volatile composition such as a perfume composition located on the surface and/or in the interstices of a planar pliable porous substrate such as a towel section. A planar surface of the substrate which contains the volatile composition is initially juxtaposed adjacent a solid wall (e.g., glass frit) porous to a nonreactive carrier gas such as air, nitrogen or carbon dioxide, and fully and tightly covers the porous section of the wall. The carrier gas is passed through the porous section of the wall and then through the pliable porous substrate section which is adjacent to the wall; after which the carrier gas contains each component of the volatile composition. The composition-carrier gas mixture is then passed through a trapping substance (e.g., TENAX® a polyphenylene oxide) which entraps the molecules of each component of the volatile composition. The thus-collected volatile composition may be subsequently analyzed (e.g.

In another embodiment of the invention is a stain removal wipe, which contains a fragrant aqueous system with low solvent and substantially free of surfactant.

Abstract: Described is a permanently and continuously fragrance-emitting dry or wet wipe laminar fabric article comprising a non-woven fabric lamina having woven therethrough and substantially throughout at least a major portion of the lamina surface at least one continuous fragrance-containing thermoplastic, substantially water-insoluble fiber, which controllably and continuously releases fragrance at least for the time period during which the fabric article is in use. Such fragrance may also have antimicrobial properties. Optionally, one or more antimicrobial substances may also be releasably contained in the fiber containing the fragrance or in a fiber apart therefrom. The fabric article optionally contains additional fragrance and/or antimicrobial agent absorbed in or adsorbed on the non-woven fabric lamina.
