Abstract:
A method for promoting the growth of yeast by using the electric field is provided to reduce the time to be required for fermentation of liquor including beer and wine and bread, and increase the production efficiency of bio-ethanol. The yeast growth is promoted by applying the AC(alternating current) electric field or DC(direct current) electric field of less than 1 Hz in the intensity of 1V to 100MV/m to the yeast, wherein the frequency of the electric field is less than 1muHz. The device for promoting the growth of yeast by using the electric field comprises: a vessel(1) made of insulator; two electrodes(2) adhered to the bottom of the vessel and outer surface of the lid; and an electric field applying apparatus(3) connected to two electrodes, wherein one of two electrodes is earthed, and another electrode is connected to the anode or cathode of the electric field applying apparatus.

Abstract:
A method for analyzing the intracellular protein interaction using a bimolecular fluorescence complementation is provided to analyze the interaction of proteins occurring at a natural state and the position in a cell in real time and observe the interaction and the position using only a fluorescent microscope easily, thereby being very usefully used for analyzing the interaction of the protein in the cells. A diploid recombinant organism except human includes a portion of a fluorescent protein respectively at each different chromosomes. A vector includes a connecting peptide sequence which provides softness when a yellow fluorescent protein fragment is attached to a C-terminal of a specific gene, a sequence encoding an N-terminal or the C-terminal fragment of the yellow fluorescent protein, and a sequence encoding an enzyme involving with the synthesis of a specific amino acid. A transgenic Saccharomyces cerevisiae is characterized in that the yellow fluorescent protein C terminal fragment is transformed at the end of a specific gene using a pFA6a-VN173-HIS3MX6 vector. A method for analyzing the intracellular protein interaction using a bimolecular fluorescence complementation comprises the steps of: (a) transforming a portion of an N-terminal of a fluorescent protein at an end of a specific protein gene of chromosomes in cells in haploid state and transforming a portion of a C-terminal of the fluorescent protein except the portion of the N-terminal at the end of the specific gene of the other chromosomes in the cells in haploid state; (c) respectively proliferating the transformed two cells; (d) selecting only diploids generated by crossbreeding the proliferated cells; and (e) observing the diploids using a fluorescent microscope.
