| Outline of Final Research Achievements |
ASICs(acid-sensing ion channel:1a,1b,2a,2b,3),PKD1L3 and PKD2L1 genes, which are candidates of sour taste receptor, were expressed individually or simultaneously in oocyte of Xenopus laevis. Resulting oocytes expressed ASIC1a or/and 1b genes were used for electrophysiological assay as sensor in order to screen sunstances able to decline or increase sour taste. As the result, effectiveness of decline on sour taste were observed in dialyzed fraction of natto A , wheet miso, rice miso, isoflavone and emulsion layer of culture broth of hydrocarbon-utilizing bacterium using membrane with pour size of molecular weight of 3,500. In contrast, effectiveness of increase on sour taste was observed in dialyzed fraction of natto B using same membrane.
