Abstract: A powder container includes a powder chamber for containing powder for forming images, a powder outlet formed in a face of the powder container, and a shutter assembly to open and close the powder outlet and including first and second shutters. The first shutter is movable between a sealing position to close the powder outlet and an open position to open the powder outlet and includes a pressed member to cancel retention of the first shutter at the sealing position. The second shutter includes a pressing projection that interferes with the pressed member of the first shutter and is movable between a shielding position to cover the pressed member without interference between the pressing projection and the pressed member and a releasing position to press the pressed member with the pressing projection.

Abstract: A strain that efficiently produces butyric acid and a method for producing butyric acid using the strain. Clostridium beijerinckii SIID27451-B11 strain (Accession No. NITE BP-02951), produces more butyric acid and less lactic acid and acetic acid in a culture solution after anaerobically culturing the strain at 37° C. for 72 hours, compared with Clostridium beijerinckii NBRC 109359T, which is a type strain of Clostridium beijerinckii.

Abstract: A method for producing a fermented liquid having an acidity of pH 3 to 4, including colloidal particles having a particle size not exceeding 50 nm and short-chain fatty acids. The method includes providing fermentation apparatus including a plurality set of temperature-controlled fermentation containers at each stage of the multi-stage fermentation process; using a soft water as a starter, a seed bacterial liquid comprising seven species of fermentation bacteria (International Accession No. NITE BP-02945 to NITE BP-02951) including spore-forming Clostridium bacteria, controlled under a low temperature condition, and three kinds of fermented media derived from natural materials, produced by individually fermenting respective first medium of dried soybeans, second medium of mixed medium of dried plants consisting Taiso, Kukoshi, and Ukon, and third material of honey material; and producing the fermented liquid by multi-stage fermentation process.
