    • Methods and compositions are disclosed wherein exogenous chemicals are applied to plants to generate a desired biological response. One embodiment of the present invention is a plant treatment composition that comprises (a) a water-soluble exogenous chemical and (b) an adjuvant amount of a solid inorganic particulate colloidal material. Another embodiment of the present invention is an aqueous concentrate plant treatment composition that comprises (a) a water-soluble exogenous chemical, (b) an aqueous diluent, (c) a surfactant component comprising one or more nonionic surfactant(s), and (d) an amount of a solid inorganic particulate colloidal material effective to stabilize the composition, said composition not exhibiting phase separation over a period of time T when stored in a closed container at a temperature in the range from about 15 DEG C to about 30 DEG C; T being in the range from about 1 hour to about 60 days; wherein the exogenous chemical and the surfactant are present at concentrations in the absolute or relative to each other such that, in the absence of the colloidal material, phase separation would occur during said period of time T.

    • The present invention relates to materials and methods for production of natural and unnatural D-amino acids. In particular, the present invention relates to a fermentation method for the production of D-amino acids using recombinant host cells. Specifically, the invention relates to a method for producing a D-amino acid in a cell, comprising: (a) incorporating into the cell a D-aminotransferase gene and an L-aminodeaminase gene; (b) culturing the cell in a cell culture medium; and (c) isolating the D-amino acid from the cell culture medium. The invention also relates to a method for producing D-phenylalanine in a cell, comprising: (a) incorporating into the cell a D-aminotransferase gene, an L-aminodeaminase gene and means for increasing production of phenylpyruvate; (b) culturing the cell in a cell culture medium; and (c) isolating the D-phenylalanine from the cell culture medium. The invention also relates to the preparation of recombinant cells for use in the production of enantiomerically pure D-amino acids.
    • 本发明涉及生产天然和非天然D-氨基酸的材料和方法。 特别地,本发明涉及使用重组宿主细胞生产D-氨基酸的发酵方法。 具体地说,本发明涉及一种在细胞中产生D-氨基酸的方法,包括:(a)向细胞中掺入D-氨基转移酶基因和L-氨基脱氨酶基因; (b)在细胞培养基中培养细胞; 和(c)从细胞培养基中分离D-氨基酸。 本发明还涉及一种在细胞中生产D-苯丙氨酸的方法,其包括:(a)向细胞中掺入D-氨基转移酶基因,L-氨基脱氨酶基因和增加苯丙酮酸生产的方法; (b)在细胞培养基中培养细胞; 和(c)从细胞培养基中分离D-苯丙氨酸。 本发明还涉及用于制备对映异构体纯的D-氨基酸的重组细胞的制备。
