Publication number: 20240102025Abstract: The present disclosure provides a gene combination for expressing and producing terrequinone A in Escherichia coli and use thereof. The gene combination includes a tdiAS gene, a tdiBS gene, a tdiCS gene, a tdiDS gene, a tdiES gene, an sfpS gene, an ScCKS gene, and an AtIPKS gene with nucleotide sequences set forth in SEQ ID NOS:1 to 8. In the present disclosure, a recombinant engineered strain capable of producing terrequinone A having anti-cancer activity is obtained by separately constructing recombinant plasmids pC02 and pU03 through the eight genes and transforming the two recombinant plasmids into E. coli. The content of terrequinone A in a fermentation broth thereof is 106.3 mg/L, which has potential application value in the biopharmaceutical field.Type: ApplicationFiled: May 24, 2023Publication date: March 28, 2024Inventors: Yongsheng TIAN, Lijuan WANG, Yongdong DENG, Quanhong YAO, Rihe PENG, Jianjie GAO, Zhenjun LI, Wenhui ZHANG, Bo WANG, Jing XU, Yu WANG, Xiaoyan FU, Hongjuan HAN

Patent number: 11634720Abstract: The technical field of preparation of organic compounds, and particularly to yeasts producing tyrosol or hydroxytyrosol and construction methods thereof. PcAAS and ADH-encoding DNA sequences are introduced into the yeast strain BY4741, to obtain a PcAAS-ADH recombinant yeast producing tyrosol. A PDC1 knockout cassette and a TyrA expression cassette are introduced into the PcAAS-ADH recombinant yeast to obtain a PcAAS-ADH-?PDC1-TyrA recombinant yeast producing tyrosol. A HpaBC encoding DNA sequence is introduced into the PcAAS-ADH-?PDC1-TyrA recombinant yeast, to obtain a PcAAS-ADH-HpaBC-?PDC1-TyrA recombinant yeast producing hydroxytyrosol. The construction of a tyrosol or hydroxytyrosol biosynthesis pathway in the yeast strain BY4741 enhances the production of tyrosol or hydroxytyrosol.Type: GrantFiled: April 16, 2019Date of Patent: April 25, 2023Assignee: SHANDONG HENGLU BIOTECH. CO., LTD.Inventors: Xu Fang, Wei Guo, Lijuan Han

Publication number: 20220327398Abstract: A technology maturity judgment method based on science and technology data comprises establishing a database, an algorithm library, and an index library, and further comprises: performing a data retrieval in the database; performing a data calculation and organization on a retrieval result; performing a regression calculation on organized data to obtain a technical maturity index; and obtaining a judgment conclusion according to the technical maturity index. The technology maturity judgment method is mainly based on a patent analysis method, which assisted by technical data analysis of papers and projects. Technical points are placed in a technology cluster associated with the technology to perform a comprehensive analysis by multi-dimensional evaluation indexes and algorithm. Mapping between science and technology data indexes and technology maturity is established and automatic judgment is achieved. The method does not need a large amount of artificial subjective work.Type: ApplicationFiled: June 27, 2022Publication date: October 13, 2022Applicant: BEIJING BENYING TECHNOLOGIES CO., LTD.Inventors: Lijuan HAN, Chang LIU

Patent number: 9644497Abstract: An integrated single-piece exhaust system (SPEX) with modular construction that facilitates design changes for enhanced aerodynamics, structural integrity or serviceability. The SPEX defines splined or curved exhaust path surfaces, such as a series of cylindrical and frusto-conical sections that mimic curves. The constructed sections may include: (i) a tail cone assembly fabricated from conical sections that taper downstream to a reduced diameter; or (ii) an area-ruled cross section axially aligned with one or more rows of turbine struts; or both features. Modular inner and outer diameter inlet lips enhance transitional flow between the last row blades and the SPEX, as well as enhance structural integrity. Modular strut collars have large radius profiles between the SPEX annular inner diameter and outer diameter flow surfaces, for enhanced airflow and constant thickness walls for uniform heat transfer and thermal expansion. Scalloped mounting flanges enhance structural integrity and longevity.Type: GrantFiled: November 22, 2013Date of Patent: May 9, 2017Assignee: SIEMENS ENERGY, INC.Inventors: Anil L. Salunkhe, John A.
