Choneophora trispora 단독 혹은 혼합배양하여 Carotene과 Vitamin A의 생성을 연구하였다. 1) $\beta$-Carotene 생성량은 chonephora trispora의 (＋)주보다 (－)주가 좋았고 단독배양보다 혼합배양이 좋았다. 2) $\beta$-cionone은 $\beta$-carotene 생합성을 촉진하였다. 3) FeCl$_3$은 균생육과 $\beta$-carotene 생합성을 저해하였다. 4) 균체추출물은 ergosterol, carotene은 확인할 수 있으나 vitamin A는 확인 할수 없었다.

Cheese제조에 이용할 수 있는 우유응고효소를 미생물 발효로써 생산할 목적으로 먼저 자연계에서 균주를 분리 선정하였다. 토양 및 메주로부터 분리한 200주의 미생물 가운데 약 50주가 2시간 이내에 curd를 형성하였으나 대부분이 proteolytic activity가 너무 커서 그대로는 이용할 수가 없음을 알았다. 그중에 유망한 균주 하나를 pH를 달리하여 배양해 보았더니 acid쪽에서 neutral보다 clotting/proteolytic ratio가 1.7배나 증가함을 확인하였다.

A total of 424 plants was regenerated from the seed-culture of a rice cultivar, 'Ilpum'. The regenerated plants were grown in a greenhouse. The 297 plants with high fertility were selected among 424 plants. The harvested seeds from each plant were planted to each line at experiment field in 2008 and 2009. The each line was evaluated for the agronomic and morphological traits, also. The 64 lines (21.5%) showed significant differences in agronomic and morphological traits from donor cultivar 'Ilpum' among 297 lines. The heading date different from donor cultivar 'Ilpum' showed highest frequency in 297 lines, and accounts for 9.1% (29 lines). The phenotype of opaque endosperm and rolling leaf account for 1.7% and 1.3% in 297 lines, respectively. The genetic segregation was observed in dwarf/semi-dwarf, rolling leaf and opaque endosperm at $S_1$ generation, but not in $S_2$ generation. These results suggest that the mutant derived from a tissue-culture will be one of the promising genetic resources, due to its wide variation and high frequency of mutation, comparatively.
