  • Recombinant bagworm silk
    Patent number: 11220529
    Abstract: A method of producing a transgenic silkworm that spins bagworm silks and producing a large quantity of bagworm silks by transgenic technology is developed and provided. A gene encoding a modified bagworm Fib H and a transgenic silkworm in which the gene is introduced, wherein the gene is obtained by cloning a gene fragment encoding a bagworm Fib H-like polypeptide comprising a partial amino acid sequence of bagworm Fib H, and fusing the gene fragment to a gene fragment encoding silkworm-derived Fib H, are provided.
    Type: Grant
    Filed: October 16, 2017
    Date of Patent: January 11, 2022
    Assignee: NATIONAL AGRICULTURE AND FOOD RESEARCH ORGANIZATION
    Inventors: Naoyuki Yonemura, Tetsuya Iizuka, Kenichi Nakajima, Takuya Tsubota, Takao Suzuki, Hideki Sezutsu, Tsunenori Kameda, Taiyo Yoshioka

  • Exogenous gene expression vector, transformant discrimination marker, and transformant
    Patent number: 9828611
    Abstract: This invention is intended to develop a promoter that can strongly induce marker gene expression throughout an embryo, so as to simply, efficiently, and accurately identify a transgenic insect at an early developmental stage, and to provide a gene expression vector into which such promoter has been incorporated as a transformant discrimination marker. Such exogenous gene expression vector comprises a polynucleotide comprising the nucleotide sequence as shown in SEQ ID NO: 1 as a promoter.

  • Soil modifier
    Patent number: 6682577
    Abstract: The soil modifier includes a porous material obtained by dry distillation of refuse-derived fuel to pioneer a cheap way for effectively utilizing the refuse, thereby enabling the environment to be improved by modification of soil while promoting environment preserving disposal of the refuse. The porous material includes carbon, nitrogen, sulfur, phosphorus, potassium, and zinc.

  • Formed product made from refuse derived fuel and method for production thereof
    Publication number: 20030069133
    Abstract: This application provides an invention of a molded product comprising a carbonaceous material having a carbon content of 30 to 70 mass % obtained by dry distillation of solidified refuse fuels and a binder. Since the molded product can be utilized as an environment cleaning material such as for foul water cleaning as it is or after processing, it can provide a stage of effectively utilizing refuses and promote consumption thereof.
