  • Method of inducing genetic recombination, and use therefor
    Patent number: 11464182
    Abstract: A method of inducing genetic recombination, including: allowing a protein having DNA double-stranded cleavage activity to act in cells of a eukaryotic organism which is a polyploidy inherently possessed by a eukaryotic organism. In eukaryotic organisms, various genetic recombination generates new genome set composition. This is done to obtain a population of eukaryotic organisms that hold the modified genomic set.
    Type: Grant

  • Method for producing useful substance from cellulose-containing material
    Patent number: 9587254
    Abstract: The present invention provides a method for producing a useful substance efficiently from cellulose without using any cellulase preparation. According to the disclosures of the present specification, in the production of a useful substance from a cellulose-containing material, the cellulose-containing material is brought into contact with an ionic liquid to cause the ionic liquid to permeate the cellulose-containing material, and a carbon source comprising the cellulose in the cellulose-containing material is simultaneously saccharified and fermented by a cellulase-producing microorganism in the presence of the ionic liquid.

  • METHOD FOR TREATMENT OF CELLULOSIC BIOMASS AND METHOD FOR PRODUCTION OF SUGAR, ALCOHOL, OR ORGANIC ACID FROM CELLULOSIC BIOMASS
    Publication number: 20130302854
    Abstract: This invention is intended to improve saccharification efficiency by allowing cellulose and/or hemicellulose to relax sufficiently with an ionic liquid. Cellulose and/or hemicellulose is allowed to relax sufficiently with an ionic liquid through a step of soaking cellulosic biomass in a solution containing an ionic liquid and an alkali.

  • METHOD OF TREATING PLANT BIOMASS
    Publication number: 20130130328
    Abstract: Plant biomass is immersed in a solution that contains a polar solvent and an imidazolium salt that has a melting point of at least 100° C. As a result, the cellulose and hemicellulose present in the plant biomass are relaxed (decrystallized and depolymerized) and brought into an easy-to-degrade state. Reacting the immersed plant biomass with a cellulase produces saccharide at a high conversion efficiency.
