    • 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.
    • 旨在提供赋予微生物细胞等的方法,对包含甲酸和乙酸的短链脂肪酸的耐受性,其对生长有害,而不抑制细胞生长,同时保持高生产率 的有用物质。 还提供了在短链脂肪酸存在下有效培养微生物的方法,或者是通过发酵生产有用的短链脂肪酸的方法。 本发明提供一种育种细胞以改善对短链脂肪酸耐受性的方法,其中将编码具有从细胞内部输送到外部的短链脂肪酸的功能的蛋白质的基因转化到细胞外, 在细胞中表达; 用于使用该细胞产生有用物质的高细胞密度培养方法; 以及制备包含短链脂肪酸的发酵液的方法,其中所述细胞在使细胞产生短链脂肪酸的条件下培养。

    • The present invention is intended to provide novel genes participating in acetic acid tolerance of acetic acid bacteria, and a method of improving acetic acid tolerance of microorganisms, particularly that of acetic acid bacteria by using the genes, further a method of efficiently producing vinegar with acetic acid at higher concentration by using acetic acid bacteria whose acetic acid tolerance is improved. In the present invention, novel genes having a function for improving acetic acid tolerance on practical level were cloned from practical acetic acid bacteria belonging to the genus Gluconacetobacter by a method of obtaining genes from chromosomal DNA library that enable to grow on the medium at a high concentration of acetic acid. Further, in transformants in which the genes were introduced into acetic acid bacteria, acetic acid tolerance was remarkably increased, and when the transformants are subjected to aeration culture in the presence of ethanol, the growth lag-time can be shortened, and the growth rate can also be improved, moreover the final acetic acid concentration can be remarkably improved.
    • 本发明旨在提供参与乙酸菌的乙酸耐受性的新基因,以及通过使用该基因来提高微生物,特别是乙酸菌的乙酸耐受性的方法,还提出了一种有效生产乙酸醋的方法 通过使用醋酸耐受性提高的乙酸菌,浓度较高的酸。 在本发明中,通过从染色体DNA文库获得能够在培养基上高生长的基因的方法,从属于葡糖型醋杆菌属的实用乙酸菌克隆了具有实用水平提高乙酸耐受性的新型基因 乙酸浓度。 此外,在将基因导入乙酸菌的转化体中,乙酸耐受性显着增加,当转化体在乙醇存在下进行通气培养时,可以缩短生长滞后时间,生长速度 也可以改善,而且可以显着提高最终的乙酸浓度。

    • A food information management system includes a food database (11) containing food cooking conditions for cooking foods, and nutritive ingredients, energy-producing values and weight of foods, and information storage mediums (20, 20a). Each information storage medium is attached to a food package (21a) containing a processed food (21) and storing food information including food ID information specifying a food. When cooling the processed food (21), the food ID information stored in the food information storage medium (20, 20a) is read by a read means. Food information about a food specified by the food ID information is retrieved from the food database (11), an output means receives the food information, and a display means displays the food information.
