1. A method for inhibiting an increase in viscosity of a culture solution of Rhizobium bacteria, the method comprising culturing a Rhizobium bacterium by liquid culture using a medium comprising one or more carbon sources, wherein a disaccharide accounts for at least 25 mass % of the one or more carbon sources in the medium while maintaining a pH of 5.0 to 7.0 in a culture solution from a beginning of the culturing to an end of the culturing,
wherein the disaccharide is at least one selected from the group consisting of maltose, trehalose, and lactose, and
wherein the Rhizobium bacterium is a Rhizobium vitis ARK-1 strain with accession number FERM BP-11426, a Rhizobium vitis ARK-2 strain with accession number FERM BP-11427, a Rhizobium vitis ARK-3 strain with accession number FERM BP-11428, or an Agrobacterium radiobacter K84 strain.
