In terms of awareness of Korean traditional food, elementary students are most affected by their parents. The objective of this study was to analyze upper grade elementary students’ parental awareness and preference of Korean traditional foods in the Chungnam Area. In a survey of 126 parents, 58% of subjects were interested in Korean traditional foods, but there was no significant difference according to age. About 87% of parents thought that inheritance of knowledge on Korean traditional foods was needed. The reasons for inheritance of knowledge on Korean traditional foods were ‘To stick to style of Korean traditional foods’ (68.2%), ‘Palatable’ (21.8%), ‘Education for children’ (6.4%), and ‘Beautiful and fine custom’ (3.6%). The awareness point of ‘Korean traditional foods are easy for cooking’ increased with increasing age (p<0.01). In all age groups, subjects highly recognized that Korean traditional foods are good for health. There were significant correlations between overall preferences for Tteok and Hankwa (r=0.351, p=0.001), Hankwa and Korean traditional drink (r=0.374, p=0.001), and Korean traditional drink and Tteok (r=0.406, p=0.001). As a result, preferences for other items also increased when preference for one of the three traditional foods increased. Therefore, education on Korean traditional foods is necessary in order to satisfy parental preferences.

Saccharomycopsis lipolytica ATCC44601과 온도감수성 변이균주인 MX9-11RX8로부터 정제한 isocitrate lyase의 성질을 조사하였다. 허영온도에서 정제한 야생형균주 및 온도감수성변이균주 isocitrate lyase는 등전점(pH5.3), 35℃와 40℃ 및 45℃에서의 열 안전성 그리고 23℃와 33℃에서 threo-Ds-isocitrate에 대한 km값(약 0.2mM)에 대하여 차이가 없었으며, 온도감수성 변이균주는 33℃의 acetate 최소배지에서 유도하였을 때 효소활성은 거의 나타나지 않지만 isocitrate lyase에 해당하는 polypeptide사슬을 23℃의 허영온도에서 유도하였을 때와 거의 같은 양을 생산하였다.
