    摘要: Disclosed are a novel fructosylamine deglycase characterized by the specificity to amadori compounds of catalyzing oxidation of the compounds to produce an .alpha.-ketoaldehyde, an amine derivative and hydrogen peroxide; a method of producing the novel enzyme by cultivating microorganisms belonging to the genus Candida and having an ability of producing the novel enzyme; and a method of quantitative determination of amadori compounds by applying the novel enzyme to a sample containing amadori compounds to measure the amount of the hydrogen peroxide to be formed by the oxidation reaction or measure the amount of the oxygen to be consumed by the reaction to thereby obtain the amount of the amadori compounds from the measured value. The invention provides a novel enzyme characterized by the high specificity to the reaction with amadori compounds, especially that having therein a saccharide moiety as bonded to the .epsilon.-amino group, and also provides a method of producing the enzyme and a method of quantitative determination of amadori compounds with the enzyme. Using the enzyme, quantitative determination of amadori compounds, which is difficult by conventional enzymatic methods, is possible with ease. In particular, in measurement of the amount of a saccharified protein in a sample from a living body, which is an important index substance in diagnosis of diabetes, the enzymatic method of the invention of measuring fructosamine in the sample is hardly influenced by other interfering substances or impurities in the sample, the influence by them having been inevitable in conventional chemical methods. Accurate determination of the amount is possible by the method, and the method is free from the inconvenience of staining the kits and instruments used. For measuring glycohemoglobin, the method displays another characteristic feature that its operation is more simple and needs less labor and time than conventional methods.

    摘要: The present invention relates to a BOD analyzer comprising a microbe sensor containing an oxygen electrode and a microbe membrane. The microbe membrane is made by immobilizing microorganisms belonging to the genus Klebsiella in membrane. Specifically, the present invention relates to a BOD analyzer comprising flow cell equipped with a microbe sensor containing an oxygen electrode and a microbe membrane; and a liquid passage which is connected with the entrance of the flow cell and which is equipped with an outlet. The microbe membrane is made by immobilizing microorganisms belonging to Klebsiella oxytoca 12092 strain in a porous hydrophilic membrane having an average pore size of 0.65-3 .mu.m in diameter by using at least one gelating agent selected from the group consisting of alginic acid or salts thereof, agar, gellan gum, xanthane gum, gelatine, carageenan, locust bean gum, methylcellulose, pectin, and pullulan. The present invention also relates to improved methods of analyzing BOD by using the BOD analyzer.

    摘要: A finished vinegar having an acetic acid concentration higher than 20 percent weight by volume is produced by repeating a fermentation cycle wherein a broth is fermented at 27.degree.-32.degree. C. in a 1st submerged fermentation tank by a continuous batch process, and, when the acetic acid concentration of the fermenting broth reaches 12-15 percent weight by volume, the large part of the fermenting broth in the 1st fermentation tank is withdrawn and charged in a 2nd submerged fermentation tank. The 1st fermentation tank is recharged with a mash and the fermentation of the fermenting broth in the 2nd tank is continued under aeration while lowering the temperature of the fermenting broth in such manner that the final fermentation temperature does not fall below 18.degree. C. and the lowering temperature does not become higher than the temperature once lowered.
