    摘要: 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.

    摘要: A target-specific image-enhancing agent for medical imaging comprises an extended poly(amino acid), wherein at least 90 percent of the amino acid residues are conjugated to signal-generating moieties attached to signal-controlling moieties via bonds that are cleavable by a physiological substance produced by the target. The image-enhancing agent becomes activated when the bonds is cleaved by the physiological substance. The image-enhancing agent is used in detecting and/or diagnosing a disease that is characterized by an overproduction of the substance.
