摘要:
Provided is a method whereby walnut can be simply, rapidly and accurately separated and distinguished from pecan nut. The method involves a PCR method for specifically detecting nuts of the family Juglandaceae and identifying the matK sequence of pecan nut to thereby discriminate walnut and pecan nut from each other optionally using restriction enzymes.

The first primer of the invention is a primer which, when used in PCR under appropriate conditions, serves to detectably amplify 16S rRNA-encoding DNAs of bacteria of the Escherichia, Salmonella and Vibrio genera, but when used in PCR under the same conditions, does not serve to detectably amplify either chloroplast 16S rRNA-encoding DNAs or mitochondrial 16S rRNA-encoding DNAs. The second primer of the invention is a primer which, when used in PCR under appropriate conditions, serves to detectably amplify 16S rRNA-encoding DNAs of Staphylococcus aureus and Bacillus cereus, but when used in PCR under the same conditions, does not serve to detectably amplify either chloroplast 16S rRNA-encoding DNAs or mitochondrial 16S rRNA-encoding DNAs.

摘要:
A rewritable indication device layer on which visible information is rewritably recorded and erased, is formed on a label base layer. A protection layer for protecting the rewritable indication device layer is formed on the rewritable indication device layer. The rewritable indication label for a recording medium having such structure, is adhered to a recording medium or a recording medium case.

The present invention relates to an apparatus for running a car at constant speed, the apparatus controlling the car to run at a desired speed, wherein by a control circuit (21), both a car-speed deviation and an acceleration are taken as variables, and a pulse-width of pulse signals having a predetermined period is computed from a function for defining pulse-width, and the above-mentioned pulse is given to an actuator (12) for adjusting opening of a throttle valve (13), thereby quickening to settle down to a set car-speed, to enable to stably run at constant speed. Moreover, resetting device (9), (220), second constant-speed-running canceling device (11), (219) which cancel a state of constant-speed-running only by operation of a canceling switch (8), (28), and checking device (10) for checking memory data are provided, thereby improving safety and reliability of control.

摘要:
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.

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 method for preventing or treating metabolic syndrome by administering bezafibrate. Since bezafibrate suppresses the action of 11β-hydroxysteroid dehydrogenase type 1 and also accelerates expression of adiponectin receptor, it is used as an agent for preventing or treating metabolic syndrome.
