  • Patent number: 11352602
    Abstract: The present invention provides methods for making microalgal strains with improved properties relative to the strains from which they are derived. In illustrative embodiments, the methods are performed to produce microalgal strains adapted for use in the industrial production of microalgae-derived biomass products, including but not limited to triglycerides and fatty acids. Also provided are microalgal strains, which can be obtained using the methods described herein, as wells microalgal-derived biomass products, which can be produced from such microalgal strains.

  • Publication number: 20190080318
    Abstract: A virtual currency storage and transaction system includes a first terminal and a second terminal. The first terminal is in a state of network disconnection, for generating a private key for encrypting a virtual currency wallet according to a seed password and a customized password and generating a storage address with an identification code corresponding to the private key, so as to receive the virtual currency paid to the storage address; also for paying the virtual currency to a third party corresponding to the payment address according to the input payment address. The second terminal is in a state of network connection, for issuing transaction information for payment of the virtual currency to the third party. The first and second terminals mutually scan the identification code on the display interface for information interaction.

  • Patent number: 9856445
    Abstract: Methods and systems for the isomerization and fermentation of xylose and hexose sugars using an immobilized enzyme system capable of sustaining two different pH microenvironments in a single vessel are disclosed. Bilayer particles are dispersed in a mixture comprising an ionic borate source and xylose. The bilayer particles have a first region with a first enzymatic activity comprising xylose isomerase and a pH of 6 or above, and a second region having a second enzymatic activity at an acidic pH.
