  • Patent number: 11421255
    Abstract: A method for enzymatic preparation of fludarabine phosphate, comprising reaction of fludarabine with a high-energy phosphate compound under the action of deoxyribonucleic acid kinase. According to said method, acetate kinase and acetyl phosphate free acid or acetyl phosphate are also added. The technical problems present in the existing processes are successfully addressed by employing the enzymatic process to prepare the fludarabine phosphate. The usage of the high-energy phosphate compound is reduced by means of adding acetate kinase to recycle and regenerate a small amount of the high-energy phosphate compound, thereby reducing the generation of by-products having similar structures to the fludarabine phosphate, enhancing the operation convenience of purification steps in the industrial production of the fludarabine phosphate. The process is environment friendly, the reaction conditions are moderate, the cost is low, and the yield and the purity of the product obtained are high.

  • Patent number: 10662420
    Abstract: Methods and devices are provided for pre-treatment of a sample containing microbial cells. In some embodiments, the pre-treatment of the sample is performed via the initial selective lysis, within a sample pre-treatment vessel, of non-microbial cells, such as blood cells, and the subsequent centrifugal separation of the sample to remove the resulting debris and concentrate the microbial cells. An immiscible and dense cushioning liquid may be included for collecting the microbial cells adjacent to the liquid interface formed by the cushioning liquid upon centrifugation of the pre-treatment vessel. After removal of a substantial quantity of the supernatant, resuspension of the collected microbial cells, and re-establishment of the cushioning liquid interface, at least a portion of the remaining suspension may be removed without substantially removing the cushioning liquid. One or more intermediate wash cycles may be performed prior to extraction of the remaining suspension, which provides a “pretreated” sample.

  • Patent number: 10385304
    Abstract: Methods and apparatus for growing photosynthetic organisms lacking Photosystem II (PSII) function using externally supplied electrons shuttled into the organism using redox mediators to improve photosynthetic output and to produce and recover chemicals of interest. By removing PSII, all PAR photons are funneled toward Photosystem I, thereby significantly increasing the theoretical photon utilization efficiency for CO2 fixation, energy storage and the capacity to synthesize valuable chemicals. Additional genetic modification can be performed to insert or enhance specific metabolic pathways to generate products of commercial interest.
