Abstract: A method and apparatus for measuring the particle diameter of foam on a malt alcoholic drink, which can detennine the quality of the foam of the malt alcoholic drink objectively, are provided. The apparatus for measuring the particle diameter of foam on a malt alcoholic drink according to the present invention includes a laser light source for irradiating a linear laser beam onto the surface of a foam layer created on a malt alcoholic drink, an imaging device for imaging a laser line reflected on the surface of the foam layer to obtain an image of the laser line, and a calculating device for obtaining edge information of the laser line from the image of the laser line to calculate the particle diameter of foam in the foam layer based on the edge information.

Abstract: The method of producing a malt alcohol beverage according to this invention is characterized in that in the production of the malt alcohol beverage an adsorbent is used to remove through adsorption at least a part of rough flavor components from malt, a malt alcohol beverage intermediate product, or the malt alcohol beverage. Such method of producing a malt alcohol beverage enables to provide a method of producing a malt alcohol beverage such that the aging of flavor after production can be suppressed and the flavor immediately after production can be maintained over a prolonged period of time.

Abstract: This invention relates to DNA containing a gene encoding uricase, a plasmid having said DNA, a transformant containing said plasmid, and a process for producing uricase by using said transformant.

Abstract: This invention relates to an isolated uricase which is stable in an aqueous solution at a temperature up to 60.degree. C. and at a pH of 8.0 for 10 minutes.

Abstract: Different from conventional uricase products, the uricase of the present invention has outstandingly high thermal stability and is active in a wide range of pH from 5 to 10 for the oxidative decomposition of uric acid undertaken in clinical analysis. The uricase of the invention is produced microbiologically by a thermophilic microorganism belonging to the genus of Bacillus and especially named as Bacillus sp. TB-90 which is a novel species distinguishable from any of the microorganisms belonging to the genus of Bacillus.

Abstract: Different from conventional urease products, the urease of the present invention has excellent stability, and has a smaller Km value. The urease of this invention is produced microbiologically by a thermophilic microorganism belonging to the genus of Bacillus and especially named as Bacillus sp. TB-90 which is a novel species distinguishable from any of the microorganisms belonging to the genus of Bacillus.

Abstract: Dextransucrase synthesis of dextran from sucrose is inhibited by a novel homocitric acid oligoriboside derivative and its nontoxic salts. The new derivative is obtained by fermentation of certain Streptomyces sp. such as Streptomyces sp. MF 980-CF1 (FERM-P5430; ATCC 31820) and is useful in the prevention of dental caries.
