Antialgal mechanism of growth-inhibitor isolated from marine micoralga of Isochrysis galbana
In order to probe the antialgal mechanism of the growth-inhibitor of 1-[hydroxyl-diethyl malonate]-isopropyl dodecenoic acid that isolated from Isochrysis galbana cultural liquid, the effect of the growth-inhibitor on the cell growth, contents of chlorophyll, extracellular protein, polysaccharide an...

| description | In order to probe the antialgal mechanism of the growth-inhibitor of 1-[hydroxyl-diethyl malonate]-isopropyl dodecenoic acid that isolated from Isochrysis galbana cultural liquid, the effect of the growth-inhibitor on the cell growth, contents of chlorophyll, extracellular protein, polysaccharide and malondialdehyde (MDA), and the activities of nitrate reductase (NR), superoxide dismutase (SOD) and peroxidase (POD) in the cells of six species of microalgae (Chaetoceros muelleri, Chaetoceros gracilis, Phaeodactylum tricornutum, Nitzschia closterium, Platymonas elliptica and Dunaliella salina) was investigated. The results indicate that the growth of all test microalgae could be strongly inhibited by the growth-inhibitor in a concentration-dependent manner. The further investigation found that the content of chlorophyll was significantly decreased, MDA, extracellular protein and polysaccharide increased obviously in all test microalgae cells when the inhibitor was added into those cultural liquid. And the activities of NR, SOD and POD in the cells of these microalgae also were inhibited or stimulated significantly by the growth-inhibitor. It was clear that through controlling the synthesis process of some key biochemical compounds and the activities of enzymes in the cells of microalgae, the antialgal mechanisms of the growth-inhibitor was set up. |
