    摘要: In a process for the preparation of a phenolic resin, a phenol is reacted with a peroxidase or an oxidase enzyme and a peroxide in an organic solvent containing medium to generate phenolic radicals which react to form phenolic resins and, more particularly, formaldehyde-free resins of formula (I), where n is an integer greater than or equal to 2, the phenolic units of the resin are directly bonded to one another through positions ortho or para to the hydroxyl group, Y is present at a position meta or para to the hydroxy group and is selected from the group consisting of an alkyl group, a halogen atom, an aryl group, a phenylalkyl group, an allyl group, a carboxyl group of the formula -COOR, where R is a hydrogen atom, an alkyl group or a phenylalkyl group, an amino group of the formula -NR1R2 where R1 and R2 are the same or different and represent a hydrogen atom or an alkyl group, and Z is a hydrogen atom, an alkyl group, a halogen atom, an aryl group, a phenylalkyl group, or a -COOR group, or Z in conjunction with the adjacent meta position forms a condensed benzene ring; or a metal-modified, formaldehyde-free phenolic developer resin obtained by reacting said developer resin with a metal salt; the resins are useful as developers in forming colored images by reaction with substantially colorless electron-donating compounds.

    摘要: Disclosed are novel DNA sequences susceptible to expression in a microorganism in the form of synthesis of one or more enzymes participative in the microbiological oxidative degradation of a selected aromatic hydrocarbon substrate to a selected oxidized compound which is an intermediate in a multiple enzyme-catalyzed degradative pathway for total mineralization of said substrate. The DNA sequences are characterized by being substantially free from operative association with DNA sequences susceptible to expression in the form of synthesis of one or more enzymes participative in oxidative degradation of said selected intermediate compound. Illustrative of the invention is a plasmidborne DNA sequence of Pseudomonas putida origin which codes for expression, in a host microorganism such as E coli, of enzymes participative in the oxidative degradation of naphthalene to salicylate. Cultured growth of stably transformed host cells in a medium including a naphthalene substrate results in quantitative naphthalene degradation and accumulation of isolatable quantities of, e.g., salicylate products.

    摘要: A method of processing plant cell cultures based on fruit explants is described, comprising the steps of: a) inducing callus from an explant of a fruit selected from drupes, nuts, legumes or berries on callus induction medium and propagating the callus on callus growth medium; b) selecting a callus clone from the grown callus culture and initiating a suspension cell culture comprising dedifferentiated cells by inoculating the selected callus clone into a suspension cell culture medium; c) growing fruit suspension cells for a time and under conditions sufficient to produce a suspension including a biomass comprising secondary metabolites; and d) separating the biomass from the suspension to provide a liquid phase and a solid, in vitro-manufactured biomass and optionally extracting secondary metabolites from the in vitro -manufactured biomass to provide a secondary metabolite extract, wherein the fruit is selected from and the explant contains endocarp and/or seed material from the drupes, nuts, legumes or berries. The method enables biomass to be manufactured in vitro at improved efficiencies and yields. In addition, in vitro-manufactured biomass prepared by the aforementioned method, uses of the same, and related food compositions are described.
