There are many yeast strains have been discovered for industrial usage in global scale. In the point of view for the alcoholic fermentation performance and producing alcoholic beverage products, recently many countries have known about the importance of microorganisms as a valuable resource. Discovered with well performed yeasts have potential industrial application in diverse ways such as foods, beverages, cosmetics, pharmaceutical functions, and so on. In Korea, the yeast research has not been sufficiently performed especially for distilled spirits industry. As a result, not so little manufacturers use exotic yeasts from overseas even included the expensive royalties. Besides of those, to produce distilled spirits, many manufacturers do not use specialized yeast for distilled spirits. Distiller's characterized yeasts such as whisky, brandy, vodka, Japanese shochu and awamori, are all well-known industrialized. For decades, the distillers, except us, have selected, developed, and practised yeasts in accordance with distilled spirits characters. This study is about selection and industrial application of yeasts for the Korean pot distilled spirits. Finally 7 yeast strains were selected among over 1,000 yeasts from the traditional Nuruks, through the essential related tests based on brewing and distilling science. The selected yeasts show the appropriate characteristics of distilled spirits. The result of this study could help our distilled spirits industry be activated and stand independent from the exotic microbes.

절간고구마원료주정폐액을 이용하여 단세포단백질을 생산함과 동시에 폐액의 BOD를 제거할 목적으로 우수효모를 선발하고, 선발된 효모의 배양조건을 검토한 후 3$\ell$ -jar fermenter에 의한 통기 배양을 한 결과 다음과 같은 결론을 얻었다. 폐액을 여과한 여액의 조성은 BOD$_{5}$ 15700ppm, COD 36800ppm, 환원당 3300ppm, 총질소 710ppm, 고형물51800ppm, 조회분390ppm이었다. 우수효모로 선발된 Torulopsis candida FRI YA-15를 $25^{\circ}C$에서 48시간 진탕배양하였을 때, 배양폐액에 대한 균체수율은 3.38g/$\ell$, BOD$_{5}$ 및 COD제거율은 각각 38.9%, 31.8%이었다. T. candida의 최적생육초기 pH는 4.0이었으며, 최적배양온도는 35$^{\circ}C$였다. 설정된 초기PH 및 온도하에서 3$\ell$-jar fermenter를 사용하여 통기량 2vvm, 교반속도 100rpm으로 배양하였을 때, 배양 28시간후에 최대로 생육하였으며, 그 때 배양액에 대한 균체수율은 3.2g/$\ell$였다. 건조균체의 조단백질함량은 47.98%였다.
