Abstract: A problem to be solved by the present invention is to provide one or more selected from (1) a feed comprising Lactobacillus plantarum strain L-137 or a processed product thereof and a fatty acid or a salt thereof, (2) a composition for enhancing IL-12 production, comprising Lactobacillus plantarum strain L-137 or a processed product thereof and a fatty acid or a salt thereof, (3) a composition for immunostimulation, comprising Lactobacillus plantarum strain L-137 or a processed product thereof and a fatty acid or a salt thereof, and (4) a composition for bacteriostasis, comprising Lactobacillus plantarum strain L-137 or a processed product thereof and a fatty acid or a salt thereof. The problem is solved by providing one or more of the feed or the compositions.

Abstract: The media-circulation type pulverizer comprising: an agitating member disposed in a lower region of a pulverization chamber; an annular partition wall disposed to extend upwardly in the pulverization chamber; and a media guide member provided on a lower surface of the end plate of the agitating member, wherein the annular partition wall has a height set to be ? to ? of a height of the pulverization chamber, and the media guide member has a lower end which enters a space of the inner region of the pulverization chamber located inside the annular partition wall, and wherein a vertically-extending flow straightening blade is provided between said lower portion of the media guide member and an upper portion of the annular partition wall, and the media separation member is provided on the lower end of the lower portion of the media guide member.

Abstract: The media-circulation type pulverizer comprising: an agitating member disposed in a lower region of a pulverization chamber and having a rotary shaft substantially coaxial with a central axis of the pulverization chamber; an annular partition wall disposed to extend upwardly from a position surrounding an outer periphery of the agitating member or a position radially away from the outer periphery by a given distance, so as to radially divide an internal space of the pulverization chamber to form an inner region of a pulverization chamber and an annular outer region of a pulverization chamber; a media guide member provided on a central area of a lower surface of the end plate to extend downwardly and configured to turn a mixture of a raw material slurry and pulverizing media being moved upwardly through the outer region of the pulverization chamber by an action of the agitating member, to a downward flow so as to direct the mixture toward the inner region of the pulverization chamber; a media separation member
