Abstract

In order to study optimum culture condition of yeast medium added deep seawater, we examed samples with 9 yeast strains. The growth rate were measured for Saccharomyces cerevisiae 10, 11, 12, 901 and RCY and Saccharomyces kluyvery DJ97, Saccharomyces cerevisiae YJK, JK99, CMY-28 etc.. The growth of S. cerevisiae 12 was found most active in the deep seawater(hardness 500). The growth rate of S. cerevisiae 901 on medium containing deep seawater(hardness 1000) was faster than that of the yeast on medium without deep seawater. The use of deep seawater on the growth of Sacch.cerevisiae kluyvery DJ97 revealed maximum growth under the condition of hardness 200 of deep seawater and 10％ of sugar concentration.

해양 심층수 첨가에 따른 효모 발효력과 심층수 첨가 최적 농도를 알아보기 위하여 효모균주 9종에 대하여 증식을 조사하였다. 효모균주는 Saccharomyces cerevisiae 10호, 11호, 12호, 901, RCY, Sacch.cerwisiae ktwef DJ97, Saccharomyces cerevisiae YJK, JK99, CMY-28 등이었으며, 해양 심층수는 경도 250, 500, 1000으로 조절하였고 대조군과 함께 증식력을 측정하였다 Saccharomyces cerevisiae 12호 균주가 심층수 경도 500인 시험군에서 증식력도 높았으며, Sacch. cerevisiae 901에서는 경도 1000인 시험군이 대조군에 비해 증식력이 높게 나타나 효모균주의 종류와 심층수의 첨가량에 따라 적응력이 강한 균주가 있었다. 당농도와 심층수 첨가량에 따른 Sacch. cerevisiae kluyevery DJ97의 발효력은 심층수 경도 200의 당 10％ 첨가군에서 가장 잘 증식하였다.
