Extraction, Initial Purification and Inhibitory Activity of Growth-Inhibitor Formed by Isochrysis galbana

The extraction process,initial purification and inhibitory activity of growthinhibitor that formed by Isochrysis galbana were investigated.And it was found that different factors impacting on(extraction) were as followed: pH,extraction time,the ratio of materials for extraction liquid and extraction solvent.Initial purification of growth-inhibitor was carried out by gel-filtered on Sephadex G column.The effect of temperature on the inhibitory activity of growth-inhibitor and the effect of growth-inhibitor o...
