摘要:
This invention disclosed herein provides an alcohol acetyl transferase ("AATase"), an AATase encoding gene and a yeast having an improved ester producing ability due to transformation with the AATase encoding gene. This invention also provides a process for producing an alcoholic beverage having an enriched ester flavor using the transformed yeast.
摘要:
In an optosemiconductor device including a superlattice configuration (TBQ) of first and second quantum well layers and a potential barrier therebetween, photo-excited carriers are formed in the first quantum well layer and are tunnelled through the potential barrier toward the second quantum well layer, so that the tunneled carriers are accumulated in the second quantum well layer. An electric field is applied to the superlattice configuration to expel the tunneled carriers from the second quantum well layer.

A liquid crystal display device (100) according to the present invention has a pixel (P), which includes red, green, blue and yellow subpixels (R, G, B and Y). The chromaticity of the yellow subpixel (Y) is outside of a triangle that is defined by connecting together the respective chromaticities of the red, green and blue subpixels (R, G and B). And the respective aperture areas SR, SG, SB and SY of the red, green, blue, and yellow subpixels (R, G, B and Y) and the respective transmittances TR, TG, TB and TY of their associated red, green, blue, and yellow color filters (CR, CG, CB and CY) satisfy the inequality TY>[(SR+SG+SB+SY)(TR+TG+TB)−3(SR×TR+SG×TG+SB×TB)]/3SY.
摘要:
There is disclosed a yeast strain of Candida utilis, wherein the yeast strain has been transformed with at least one copy of a gene that is operatively linked to a promoter sequence enabling expression of the gene and encodes a polypeptide having activity of lactate dehydrogenase. The yeast strain is useful for producing lactic acid with high efficiency.

The present invention relates to improved promoters and utilization thereof, in particular to promoters which are improved so as not to undergo methylation in the course of constructing transformants, and utilization thereof. According to the present invention, the expression efficiency of a structural gene can be enhanced even in a plant, e.g. chrysanthemum, which has weak expression of the structural gene by a cauliflower mosaic virus 35S promoter which as been considered a high expression promoter for plants.
摘要:
A liquid crystal display apparatus is produced by the steps of arranging pixel electrodes, TFT devices and signal wiring on one surface of one substrate, arranging a transparent layer on a portion of one surface of a transparent substrate which portion is to be a display portion, bonding the one substrate and the transparent substrate to each other while the one surface having the pixel electrodes formed thereon faces the one surface having the transparent layer formed thereon, and injecting a liquid crystal between the substrates to form a liquid crystal layer. A fluidization path of the liquid crystal can be secured in a non-display portion, too, in which the TFT devices and the signal wiring are disposed when the liquid crystal is injected. Therefore, it is possible to shorten the injection time by increasing the liquid crystal injection speed and to improve productivity.
摘要:
The object of the present invention is to provide an antiallergic composition useful to prevention/treatment of allergy, its preparation method, and its use as foods or drinks or the like. As for means for solving the object, it is to provide an antiallergic composition comprising as active ingredients the lactic acid bacteria showing equal interleukin 12 production level compared to when Lactobacillus paracasei KW 3110 strain is used as the lactic acid bacteria to be tested, or showing 60% or more of interleukin 12 production level compared to when Lactobacillus paracasei KW 3110 strain is used, and showing less than 50% of interleukin 4 production level of a control wherein the lactic acid bacteria are not added, in case lymphocytes derived from mouse spleen sensitized with ovalbumin are suspended in a medium containing ovalbumin, and cultured by adding the lactic acid bacteria to be tested. The present invention encompasses a method for obtaining the lactic acid bacteria with antiallergic activity being the active ingredients of the antiallergic composition of the present invention, and the use of the antiallergic composition of the present invention to foods and beverages and the like, and further by formulation, the use as antiallergic agent administered orally.
