摘要:
The present invention provides a rapid coulometric analysis for the quantitative determination of a sample substance wherein the coulometric analysis has high reproducibility without any application of voltage, etc., from an outside source, as well as a galvanic cell and a device for use in said coulometric analysis. According to the present invention, a wide variety of components can be analyzed by selection of electroactive substance introduced into the galvanic cell. The present invention enables a simple and easy analysis for food components such as glutamic acid, ascorbic acid, etc., water quality such as COD, etc.

This invention relates to the structural gene for the membrane-bound aldehyde dehydrogenase derived from microorganisms belonging to the genus Acetobacter, said structural gene having a molecular size of about 3.6 Kb and having a restriction enzyme cleavage map as shown in FIG. 1; to a plasmid containing said structural gene; to an acetic acid bacterium transformed by said plasmid; and to an acetic acid fermentation process using said transformant.
摘要:
An enzyme sensor, which comprises an enzyme-modified electrode and a counter electrode, wherein the enzyme-modified electrode comprises, as electrode components, an enzyme and/or an enzyme-containing substance and mediator. The enzyme sensor is useful in analysis, such as the analysis of compounds in foods or components in the living body, the diagnosis of diseases and the control of reaction processes. The preparation of the enzyme-modified electrode is also described.
摘要:
There is provided a structural gene of membrane-bound alcohol dehydrogenase complex having a molecular size of about 7.0 kilo base which is derived from a microorganism belonging to the genus Acetobacter represented by Acetobacter altoacetigenes and shown by the nucleotide sequence of SEQ ID. NO. 1 and SEQ ID NO. 2. This enzyme increases the efficiency of acetic acid fermentation and may be effectively utilized for quantitative determination of alcohol.

摘要:
It is intended to provide a method of conferring to microbial cells or the like, tolerance to a short chain fatty acid, including formic acid and acetic acid, which is harmful to the growth thereof without suppressing the growth of the cells while maintaining a high productivity of useful substances. It is also intended to provide a means for efficiently culturing a microorganism in the presence of a short chain fatty acid, or a means for producing a useful short chain fatty acid via fermentation.The present invention provides a method of breeding cells to improve tolerance to a short chain fatty acid, wherein a gene encoding a protein having a function of transporting a short chain fatty acid from the inside of cells to the outside of cells, is transformed into and expressed in the cells; a high cell-density culture method for producing useful substances using the cell; and a method of preparing a fermentation broth comprising a short chain fatty acid, wherein the cells are cultured under the conditions such that the cells produce a short chain fatty acid.
摘要:
A widthwise-stretched film is lap-sealed on one side of a backing paper, and polyethylene is extruded and coated on the surface of said film to form a release layer thereon. A pressure-sensitive adhesive composed mainly of polyacrylic ester is then coated on the other side of the backing paper. In this manner, a paper-backed adhesive tape of the pressure-sensitive type is prepared.
