  • Patent number: 11898139
    Abstract: Provided herein is a culturing method for bacteria of the genus Rhizobium whereby a low viscosity can be maintained in a culture solution during the culturing of and at the end of culturing of said bacteria, and that enables easy and efficient post-procedures, including concentration and separation of viable bacteria, among others. This is achieved by growing Rhizobium bacteria by liquid culture using a medium containing a disaccharide (for example, maltose, trehalose, lactose, sucrose) accounting for at least 25 mass % of the carbon source in the medium while maintaining a pH of 5.0 to 7.0 in the culture solution throughout the course of the culture, namely from the beginning of the culturing to the end of the culturing of said bacteria.

  • Patent number: 11639491
    Abstract: Provided herein is a method for producing a lyophilized composition of viable cells of Rhizobium bacteria having high viable cell viability, and a lyophilized composition of viable cells of Rhizobium bacteria having desirable long-storage survivability, among others. The lyophilized composition of viable cells of Rhizobium bacteria having high viable cell viability and desirable long-storage survivability can be obtained when a composition containing viable cells of Rhizobium bacteria and more than 10 mass % moisture is lyophilized to bring the moisture content to 10 mass %, and the drying is ended before the moisture content becomes less than 5 mass % so that the composition after the lyophilization contains the viable bacteria and 5 to 10 mass % of moisture.

  • Patent number: 9020576
    Abstract: A biological measurement apparatus of this invention includes (i) a micro piezoelectric element for vibrating a nerve cell of a subject without coming in contact with the nerve cell, (ii) an electromagnetic wave antenna for receiving an electromagnetic wave generated by the nerve cell vibrated by the micro piezoelectric element, and (iii) a computer for measuring an electric charge of the nerve cell based on the electromagnetic wave received by the electromagnetic wave antenna. Further, this biological measurement apparatus includes an electromagnetic wave antenna for emitting an electromagnetic wave to a nerve cell. This configuration provides an apparatus capable of measuring an electrical activity of a nerve cell in a living organism in real time and three-dimensionally at a spatial resolution of a nerve cell size. Moreover, this configuration provides an apparatus capable of individually giving electrical stimulations to any desired cells in the subject.

  • Patent number: 8927286
    Abstract: A shoot of a plant is cultivated under the presence of glutathione, so that the shoot is rooted. It is possible to cultivate the shoot under the presence of glutathione by use of a rooting medium including glutathione or by contacting a solution including glutathione with the shoot. Oxidized glutathione is preferably used as glutathione. By promoting rooting of the shoot of the plant, a rooting rate of the shoot of the plant is improved. This improves productivity of a clone seedling.

  • Patent number: 8173865
    Abstract: It is found that a transformed plant into which a ?-glutamylcysteine synthetase gene has been introduced is increased in at least one of the number of flowers and the number of seeds in comparison with a wild-type plant, and is therefore increased in seed yield. Based on this finding, the present invention elucidates the function of a product of a plant-derived ?-glutamylcysteine synthetase gene and provides a technique for producing a plant having an increased seed yield.
