  • 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: 9573399
    Abstract: Provided is an air jet emission method used in a recording apparatus. The recording apparatus performs predetermined printing by ejecting ink droplets from a recording head provided in an apparatus body onto a medium. The medium is fed into the apparatus body while being guided by a guide and is transported from an upstream side, which is one side with respect to the apparatus body, toward a downstream side, which is an opposite side with respect to the apparatus body. The air jet emission method comprises: emitting a jet of air onto a surface of the transported medium at a predetermined area over a heating device at the upstream side, thereby blowing dust off the surface of the transported medium. The heating device is provided in the guide so as to apply heat to the transported medium.
