Abstract
The crude inhibitor, ethyl acetate extracts, was obtained from the old culture liquid of Isochrysis galbana. The cultures were treated by ethyl acetate extracts in different concentration, and then the effects of this extract on the cell density, chlorophyll a, polysacchrides and proteins were investigated. The results showed that the microalgal cells were sensitive to this crude inhibitor, and the cell density, polysacchrides and chlorophyll a could be used as biological marks for researching the inhibitory affect on the growth of Isochrysis galbana.
