Patent number: 11898139Abstract: 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.Type: GrantFiled: October 23, 2018Date of Patent: February 13, 2024Assignees: Kumiai Chemical Industry Co., Ltd., K.I Chemical Industry Co., Ltd., Okayama Prefectural GovernmentInventors: Toshinobu Yamazaki, Shingo Hattori, Tatsuya Horiuchi

Patent number: 11639491Abstract: 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.Type: GrantFiled: October 23, 2018Date of Patent: May 2, 2023Assignees: Kumiai Chemical Industry Co., Ltd., K.I Chemical Industry Co., Ltd., Okayama Prefectural GovernmentInventors: Toshinobu Yamazaki, Nobutoshi Myojo, Shingo Hattori, Tatsuya Horiuchi, Akira Kawaguchi, Namiko Kirino

Publication number: 20140023547Abstract: There is provided chips for injection molding wherein the surfaces of chips made of an aluminum-containing magnesium alloy are coated with carbon powder. A molded article produced by injection molding of such chips for injection molding had excellent bending properties and tensile strength, which vary in a small range. Furthermore, a scrap formed during injection-molding of the chips for injection molding has improved recyclability.Type: ApplicationFiled: April 6, 2012Publication date: January 23, 2014Applicants: STU CO., LTD., OKAYAMA PREFECTURAL GOVERNMENTInventors: Yutaka Mitooka, Makoto Hino, Koji Murakami, Hikaru Uchiyama, Yoshiaki Hashimoto

Publication number: 20100009150Abstract: An intermediate member for laser bonding (3) to be sandwiched, in order to bond a first member (2) and a second member (4) using a laser welding method, between the first member (2) made of a material capable of transmitting laser beams and the second member (4) made of a material which is the same as or different from that of the first member (2) before irradiation with laser beams, the intermediate member for laser bonding (3) having tackiness. This intermediate member for laser bonding (3) can be used for bonding of various materials, and thus a high bonding strength can be attained.Type: ApplicationFiled: March 27, 2007Publication date: January 14, 2010Applicants: Okayama Prefectural Government, Hayakawa Rubber Co., Ltd.Inventors: Yutaka Mitooka, Kazuya Nagata, Makoto Hino, Kazuto Urakami, Kazuya Fujita
