Abstract
In this study, two species of algae, Ecklonia stolonifera, Sargassum thunbergii and one species of marine plant, Zostera marina(rhizoid and stem) were collected and extamined to determine the extractability of water soluble protein and the influences of various factors including extraction time, temperature, ratio of sample vs solvent and pH upon the extractability were tested. The effects of precipitation treatments for isolation of algal protein from the extracts(TCA treatment, methanol treatment and pH control) were also tested. Amino nitrogen and total nitrogen of purified samples made by obtained optimum conditions were estimated. The effect of the ratio of sample vs solvent on extractability differed from species to species which was enhances at 1:100(w/v) in Sargassum thunbergii and Zostera marina while 1:150(w/v) for Ecklonia stolonifera. The effect of extraction time and temperature was revealed differently in all species which might be considered to be caused by differences in the constitution of algal tissues. But in case of TCA insoluble nitrogen, it was showed the maximum extractability at
자원(資源)이 풍부한 적이용해조(赤利用海藻)를 단백질(蛋白質) 자원(資源)으로 이용(利用)하기 위(爲)하여 지충이, 잘피 및 잘피 등(等) 2종(種)의 해조(海藻)와 1종(種)의 해산식물(海産植物)을 선정(選定)하여 이의 수용성(水溶性) 단백질(蛋白質) 추출조건(抽出條件)을 검토(檢討)하였다. 1) 첨가수량(添加水量)은 곰피는 1:150(W/V)의 비(比)로 가(加)했을 때 추출효과(抽出效果)가 좋았고, 잘피와 지충이는 1:100(W/V)일 때가 좋았다. 2) 추출시간(抽出時間)은 총질소(總窒素)의 경우 2시간(時間) 이상(以上)에서, TCA 불용성(不溶性) 단백질(蛋白質)은 1시간(時間) 정도(程度)가 효과적(效果的)이었다. 3) 추출온도(抽出溫度)는
