Abstract

Phycomyces sp. has been isolated from Meju and its lipid composition was investigated. The lipid content was 18.2 % of dry weight and composed of 69.2 % neutral lipids. 24.3 % glycolipids and 6.5 % phospholipids. It was possible to identify the presence of carotene, hydrocarbons, esterified sterols, fatty acid esters, triglycerides. free fatty acids and free sterols in the neutral lipid fraction. Major components in the neutral lipid fraction were free fatty acids and triglycerides. Twelve molecular species of triglycerides and 8 molecular species of diglycerides were fractionated by argentation TLC. The major fatty acids in total lipids were stearic, linoleic, arachidic and linolenic acids, and those in the free fatty acid fraction were stearic, linoleic and arachidic acids.

재래식 메주로 부터 분리(分離)한 Phycomyces속(屬)의 포자낭병의 지질조성(脂質組成)을 분석(分析)하여 다음과 같은 결과(結果)를 얻었다. 1. 건체중(乾體中)의 지질(脂質)을 18.2%로서 그 조성(組成)은 중성지질(中性脂質)이 69.2%, 당지질(糖脂質)이 24.3% 그리고 인지질(燐脂質)이 6.5%였다. 2. 중성지질(中性脂質)의 구성성분(構成成分)은 carotene,탄화수소(炭化水素), estrified sterol, 지방산(脂肪酸) ester, triglyceride, 유리지방산(遊離脂肪酸), 유리(遊雌) sterol등이고 주성분(主成分)은 유리지방산(遊離脂肪酸)과 triglyceride로서 각각 45.6%와 30.9%를 차지하였다. 3. $AgNO_3-TLC$에 의한 방법(方法)으로 triglyceride에서 12개(個), diglyceride에서 8개(個)의 lipid molecular species를 분별(分別)하였다. 4. 총(總) 지질(脂質)의 주지방산(主脂肪酸)은 stearic, linoleic. arachidic, linolenic acid이고 유리지방산(遊離脂肪酸)의 주지방산(主脂肪酸)은 stearic, linoleic, arachidic acid 등이었다.
