  • Patent number: 11933133
    Abstract: A technique facilitates actuation of a packer to a sealing and gripping position along a borehole. The packer includes a packer element structure mounted about a center structure. The packer element structure includes a sealing element mounted along an expandable base such that the sealing element may be radially expanded. Additionally, the packer includes an actuator member connected to a portion of the packer element structure via a release mechanism, e.g. a shear member. A plurality of slips may be located on the actuator member such that linear movement of the actuator member causes successive movement of the packer sealing element and then the slips in the radially outward direction. The packer may be constructed such that this sequential setting motion creates a jarring effect to ensure the slips securely bite into the surrounding wellbore surface, e.g. casing surface.

  • Patent number: 11692178
    Abstract: A genetically engineered bacterium includes a genome of the Eschericia coli and a mutant encoding gene hisG* of a Corynebacterium glutamicum ATP phosphoribosyl transferase HisG on the genome, and the gene hisG* is strongly expressed to enhance activity of a key enzyme HisG for histidine synthesis. The gene hisG* has a nucleotide sequence as shown in SEQ ID NO: 1; a copy number of histidine operon genes hisDBCHAFI of the Eschericia coli is further increased on the genome to enhance a terminal synthetic route of histidine; an encoding gene lysE from an arginine/lysine transportprotein of the Corynebacterium glutamicum is further integrated to the genome and strongly expressed to promote the intracellular histidine secrete to the extracellular space; and an encoding gene rocG of glutamate dehydrogenase of Bacillus subtilis is further integrated to the genome and strongly expressed to promote generation of histidine.

  • Patent number: 11603545
    Abstract: The present invention discloses an engineering yeast strain for producing nervonic acids. The yeast strain over-expresses the genes related to enzymes required in a synthetic process of long-chain unsaturated fatty acids, such as fatty acid elongase, desaturase, diacylglycerol acyltransferase and the like, and optionally, further adjusts and controls the synthesis and decomposition route of triglyceride, the synthesis and decomposition route of sphingomyelin, and the synthesis and decomposition route and the oxidation-reduction balanced route of lipid subcell levels. The recombinant yeast strain can produce microorganism oil; and the content of the prepared nervonic acids accounts for 39.6% of the total fatty acids.
