摘要: A method for preparing a biogenic guanidine complex, the method including: mixing dimethyl sulfoxide (DMSO) with water in a volume ratio thereof of 1:1 to yield a solvent DMSO-H2O; adding organic guanidine (G) and a compound MX2 in a molar ratio G/MX2=1:1 or 2:1 to the solvent DMSO-H2O, where the organic guanidine (G) is selected from arginine (Arg), guanidinoacetic acid (Gaa), creatine (Cra), creatinine (Cran), guanine (Gua), and agmatine (Agm); M represents Fe2+, Mg2+, or Zn2+; and X represents Cl−, CH3COO−, or CH3CH(OH)COO−; stirring the solvent DMSO-H2O containing the organic guanidine and the compound MX2; recycling the solvent DMSO-H2O through vacuum distillation and obtaining a solid; transferring the solid to a Buchner funnel, and washing the solid with deionized water and ethanol consecutively; and removing the deionized water and ethanol through vacuum filtration, and drying the solid. Biogenic guanidine complex can be used for production of Polyethylene terephthalate or Poly(ethylene isophthalate-co-terephthalate).

摘要: Provided herein is a non-naturally occurring microbial organism having a methanol metabolic pathway that can enhance the availability of reducing equivalents in the presence of methanol. Such reducing equivalents can be used to increase the product yield of organic compounds produced by the microbial organism, such as adipate, 6-aminocaproate, hexamethylenediamine or caprolactam. Also provided herein are methods for using such an organism to produce adipate, 6-aminocaproate, hexamethylenediamine or caprolactam.

摘要: Disclosed herein is a method for converting an epoxide to a first C3 product, a second C3 product, and/or a first C4 product within an integrated system. The method includes converting the epoxide to a beta lactone to produce an outlet stream comprising beta lactone. The method includes converting the beta lactone of the outlet stream to a first C3 product in the first C3 reactor to produce an outlet stream comprising the first C3 product; converting the beta lactone to a second C3 product in the second C3 reactor to produce an outlet stream comprising the second C3 product, and/or converting the beta lactone to a first C4 product in the first C4 reactor to produce an outlet stream comprising the first C4 product.

摘要: A novel polymer is provided by polymerization of xylitol and dodecanedioic acid. The polymer, poly(xylitol-dodecanedioic acid) or PXDDA, shows high elasticity. PXDDA significantly improves cell adhesion and promotes cell proliferation compared to an FDA-approved polymer, poly(lactic acid), and tissue-culture plates. PXDDA can be synthesized by a simple melt condensation polymerization without the use of any toxic catalysts.
