The aim of the present project is to establish optimum conditions for massculture of phytoplankton living in extreme environments and to search for such useful substances as biologically active compounds and nitrogenous extractive componets produced by those plankton.1. More than 30 species of phytoplankton were collected and mass cultivated.2. Screening of biologically active compounds was carried out by means of the antimicrobial activity test and the inhibition test of development of fertilized echinderm eggs.3. A novel antifungal polyether macrolide, goniodomin A, was isolated from the dinoflagellate Goniodoma pseudogoniaulax living in the rock pool and its structure was determined on the basis of spectral data.4. Extractive nitrogenous constituents in the halotolerant green alga Dunaliella bardawil were analyzed. Approximately 45% of the constituents was accounted for by peptides, some of which showed inhibitory effects in the enzyme assay.

本项目的目的是建立极端环境中浮游植物的最佳养殖条件，并寻找这些浮游植物产生的生物活性化合物和含氮提取物等有用物质。采集并大量培养了30余种浮游植物.通过抑菌活性试验和受精卵发育抑制试验筛选生物活性化合物.从生活在岩池中的沟鞭藻Goniotropium pseudogoniaulax中分离得到一种新的抗真菌聚醚大环内酯类化合物goniodomin A，并根据光谱数据确定了其结构.分析了耐盐绿色盐藻杜氏藻（Dunaliella bardawil）的萃取性含氮成分。约45%的成分占肽，其中一些在酶测定中显示出抑制作用。
