Patents by Inventor Yoko IDE

Yoko IDE has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10597631
    Abstract: While green algae are expected to serve as raw materials of biomass fuels, they are damaged by high-intensity light when subjected to mass-culture outdoors in summer, and biomass productivity is deteriorated as a consequence. In order to overcome such a drawback, the present invention provides a high-intensity light resistant green algae mutant that can be subjected to outdoor culture in summer. Specifically, the present invention relates to such green algae mutant, wherein functions or expression levels of a protein having a response regulatory domain at the N-terminus and a WD40 domain at the C-terminus are lower than those in a wild-type strain, and wherein said green algae mutant grows faster than a wild-type strain when cultured at a light intensity of 1,000, 1,500, or 2,000 ?mol photons m?2 s?1 measured as photosynthetically active radiation (PAR).
    Type: Grant

  • Patent number: 10370687
    Abstract: It is an object of the present invention to provide the eukaryotic microalgae, which have been genetically modified such that larger amounts of assimilation products produced by photosynthesis are directed to the synthesis of triglyceride (=triacylglycerol; TAG), and specifically, the present invention relates to a genetically modified strain of eukaryotic microalgae, in which a gene encoding an AGL1 protein is highly expressed, or a gene encoding an FAT1 protein and/or a gene encoding a DGAT2 protein are further highly expressed, as well as the gene encoding an AGL1 protein, wherein TAG productivity is improved in comparison to the parent strain thereof.

  • Patent number: 10087496
    Abstract: A green alga variant having a dual-specificity tyrosine-phosphorylation regulated protein kinase activity that is reduced compared to a dual-specificity tyrosine-phosphorylation regulated protein kinase activity of a parental strain is provided. The green alga variant increases a total amount of a lipid production per unit time and per unit culture area compared to a total amount of a lipid production of the parental strain. A dual-specificity tyrosine-phosphorylation regulated protein kinase of the parental strain is a protein having an amino acid sequence with at least 50% sequence identity with the amino acid sequence of an active site and a substrate recognition site of SEQ ID NO: 4 and having the dual-specificity tyrosine-phosphorylation regulated protein kinase activity.
