摘要： 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.

摘要： 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.
