Abstract: A method for preparing polyester/polyamide polymers, resins and plastics from proteins is disclosed. Using nitrous acid or nitrous oxide, a protein is converted to a hydroxyl carboxyl polyamide protomer. Protomers are condensed through hydroxyl and carboxyl groups to make inter-protomer ester bonds, resulting in a polyester polyamide polymer, resin or plastic.

Abstract: A general process for the extraction of carotenoids from a carotenoid source such as a biomass, which may be various biomasses including the yeast Phaffia rhodozyma, comprises treating the carotenoid source at an elevated temperature with a solvent mixture comprising water, a hydrophobic carotenoid solvent such as vegetable oil and a water soluble co-solvent such as ethanol so as to extract the carotenoid source into the hydrophobic solvent. Benefits include (a) the ease of incorporation into the diet, (b) the increased bioavailability achieved and, (c) the ease of stabilization against oxidation.

Abstract: The invention provides a process for the preparation of long-chain alkyl glycosides, comprising reacting a glucose-containing reactant and a C.sub.8 -C.sub.18 fatty alcohol in the presence of a glucosidase and a reaction promoter effective to promote the formation of the alkyl glycoside when the promoter is present in an amount of less than about 50 wt % of the total reaction mixture.

Abstract: A sol-gel glass doped with one or more reagent that provides chemical interactions with diffusible solutes or components in an adjacent liquid or gas phase. The reagent(s), the solutes or the components can be any organic or inorganic compounds or materials of biological origin, including enzymes. The doped sol-gel glass in various forms is useful as an analytical test, chromatographic medium, sensor, catalyst or biocatalyst, electrode or enzyme electrode, and other detection devices.

Abstract: A metod is proposed of obtaining a chemical interaction between at least one reagent trapped in sol-gel glass by doping it with the reagent(s), and diffusible solutes or components in an adjacent liquid or gas phase. The reagents, the solutes or the components can be any organic or inorganic compounds or materials of biological origins including enzymes. The doped sol-gel glass in various forms may be useful as analytical test, chromatographic medium, sensor, catalyst or biocatalyst, electrode or enzyme electrode, or other detection device.
