| 英文摘要 | in order to investigate a new method of mitigating the deleterious effect of harmful algal blooms (HABs), the inhibition of the glycolipid biosurfactant sophorolipid on three common harmful algae Alexandrium tamarense, Heterosigma akashiwo and Cochlodinium polykrikoides was studied. The optimum preparation condition for sophorolipid, the inhibition capability of sophorolipid and the interaction mechanism of sophorolipid on the three algal species were investigated. Results showed that sophorolipid prepared by extraction with ethyl acetate exhibited the most prominent inhibition effect and that storage time of one year had little influence on the inhibition effect of sophorolipid. The optimum concentration of 10-20 mg/l sophorolipid inhibited the motility of about 90% of the tested harmful algal cells without recovery. Investigation of the algicidal process revealed that sophorolipid induced ecdysis of A. tamarense, quick lysis of H. akashiwo and swelling of C. polykrikoides in a relatively short time. Investigation of the nucleotides showed that more than 15% of the nucleotides were released from the cytoplasm under the effect of 10-20 mg/l sophorolipid, indicating the irreversible damage on the cellular membrane, which resulted in the disintegration of the harmful algal cells.
