Abstract: The present invention provides a microorganism capable of producing vitamin K or a derivative thereof with good efficiency. The present invention relates to Yunnan strain SL-001 FERM BP-6713, a new strain belonging to Bacillus subtilis.

Abstract: A method for culturing Bacillus subtilis in such a manner that a vitamin K derivative is accumulated in the largest amount in the cells of the microorganism. A method for the culture of Bacillus subtilis, which comprises culturing Bacillus subtilis and recovering the cells of the microorganism before the vitamin K produced within the cells of the microorganism is released from the cells is disclosed, as well as the cultured product of Bacillus subtilis cultured by this method, a water-soluble vitamin K derivative originating in the cultured product, a food product, beverage, or feed containing the cultured product and/or the water-soluble vitamin K derivative, and a method for extracting vitamin K.

Abstract: A releasing film (C) comprising a polyester film (A) and a cured silicone resin layer (B) formed on at least one side of the polyester film (A), characterized in that (1) the film (A) is a biaxially oriented film formed of polyethylene-2,6-naphthalenedicarboxylate and has a surface center line average roughness (Ra) of 50 nm or less and (2) the releasing film (C) has a dimensional change of 0.2% or less under a stress of 150 gf/mm2 at 120° C.; and a releasing film (C) comprising a primer layer (D) having a SiO bond, between said film (A) and said cured silicone resin layer (B). The releasing film of the present invention is excellent in heat resistance, surface properties and gas barrier properties, and has small dimensional change rate.

Abstract: A releasing film comprising: a base film produced from a polyethylene naphthalate, and a releasing layer formed on one or both sides of the base film, wherein the polyethylene naphthalate contains naphthalenedicarboxylic acid as the main acid component and ethylene glycol as the main glycol component and further contains a manganese compound, a phosphorus compound and an antimony compound in Mn, P and Sb amounts satisfying all of the following formulas (1) to (3): 0.7≦Mn≦1.6  (1) 0.5≦Mn/P≦1.2  (2) 0.7≦Sb≦2.2  (3) (wherein Mn is moles of manganese element per 106 g of acid component; P is moles of phosphorus element per 106 g of acid component; and Sb is moles of antimony element per 106 g of acid component), and the base film has a surface center line average roughness (Ra) of 2 to 50 nm.

Abstract: A release film comprising a release layer provided on at least one side of a biaxially oriented polyethylene-2,6-naphthalenedicarboxylate film, wherein:(1) the release layer is a layer formed of a resin composition consisting substantially of an acrylic resin, a silicone resin and a melamine crosslinking agent, the amount of the silicone resin being 1 to 100 parts by weight based on 100 parts by weight of the total amount of the acrylic resin and the melamine crosslinking agent, and(2) the release film has a percentage change in dimension in absolute value of 0.3% or less in both a longitudinal direction and a direction perpendicular thereto as measured at 120.degree. C. under a stress of 150 gf/mm.sup.2.The release film is useful as a protective film for formation of a coating from a coating solution containing a variety of solvents or as a carrier film for formation of a sheet or a film, and has very small percentage change in dimension at the time of heat treatment, in particular.

Abstract: The invention discloses that the tissues of earthworms contain fibrinolytically or thrombolytically active ingredients which can be extracted and purified by a suitable sequence of extraction and purification procedures into the individual active ingredients including six novel proteases named F-O-HM-45, F-I-1-HM-54, F-I-2-HM-15, F-II-HM-64, F-III-1-HM-27 and F-III-2-HM-89. The chromatographic fractionation of the earthworm extract with an aqueous extractant gives five active fractions, the first four of which contain each one of the first mentioned four proteases and the last of which contains the last mentioned two proteases. The disclosure includes description of the suitable purification methods for the proteases as well as the physico-chemical identification data thereof. Various thrombolytic medicament forms prepared with the novel proteases as the effective ingredient are described together with the results of the clinical tests carried out by the oral administration of the novel proteases.
