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
