    • This invention pertains to a method of production of 4-hydroxybenzoic acid, with purification and recovery of 4-hydroxybenzoic acid directly from the fermentation medium of a cultured organism, in the presence of other chemical species. Ion exchange resin is used during the fermentation process to recover the chemical product without the necessity of separating the biomass from the fermentation supernatant by filtration after fermentation is complete and then treating the filtrate to recover the product. This reduces or eliminates the need for filtration steps and eliminates the need for energy-intensive water removal processes. Furthermore, the removal of the product during the fermentation dramatically increases the production of the product during the fermentation process. This method therefore can both increase the amount of product produced in a single fermentation run and reduce the per unit cost of its biocatalytic production.
    • 本发明涉及一种生产4-羟基苯甲酸的方法,在其它化学物质存在下,直接从培养的生物体的发酵培养基中纯化和回收4-羟基苯甲酸。 在发酵过程中使用离子交换树脂来回收化学产品,而不需要在发酵完成后通过过滤从发酵上清液分离生物质,然后处理滤液以回收产物。 这减少或消除了对过滤步骤的需要,并且消除了对能量密集型除水过程的需要。 此外,在发酵期间除去产物显着增加了发酵过程中产物的产生。 因此,该方法可以增加在单次发酵运行中产生的产物的量并降低其生物催化生产的单位成本。

    • A method for synthesizing extended poly(amino acids) conjugated to imaging agents, such as DTPA, is disclosed. The amino acid is initially conjugated to the imaging agent at the monomer stage, followed by formation of the corresponding N-carboxyanhydride. The method utilizes catalyzed ring opening polymerization of the N-carboxyanhydride of the amino acid-imaging agent monomer allowing the formation of a poly(amino acid) backbone having 100% imaging agent conjugation if desired. However, the present method also permits the degree of conjugation to be controlled by copolymerizing the N-carboxyanhydride of the amino acid-imaging agent monomer with one or more unconjugated monomers, i.e. N-carboxyanhydrides of the same or of other amino acids. Various imaging agents may be employed, and new hybrid random, block, and mixed copolymers may be prepared.
    • 公开了用于合成与显影剂缀合的延伸的聚(氨基酸)的方法,例如DTPA。 氨基酸最初在单体阶段与成像剂缀合,然后形成相应的N-羧酸酐。 该方法利用氨基酸显影剂单体的N-羧酸酐的催化开环聚合,如果需要,允许形成具有100%成像剂共轭的聚(氨基酸)主链。 然而,本方法还允许通过使氨基酸显影剂单体的N-羧酸酐与一种或多种非共轭单体,即相同或其它氨基酸的N-羧酸酐共聚来控制缀合度。 可以使用各种成像剂,并且可以制备新的杂化随机,嵌段和混合共聚物。
