| 摘 要： | 利用生态毒理学方法研究了小球藻共栖Z-QS01菌株的生态学效应及对UV-B辐射的响应.结果表明:Z-QS01菌株通过分泌化学物质实现自我行为调节和对小球藻的抑制效应,Z-QS01菌株的密度和分泌到培养液中的化学物质的浓度是启动调节机制的必要条件;UV-B辐射增强显著影响Z-QS01菌株的群感效应,随UV-B辐射剂量的增加,Z-QS01菌株对小球藻的抑制效应降低.实验数据可为水产养殖业生态防病提供参考,并为揭示藻菌间相互作用机制提供有价值的参考资料.

| Abstract: | An associated heterotrophic dominant single bacteria-Z-QS01 was selected to study its mechanism of quorum sensing and factors that affected quorum sensing using ecotoxicological technique in co-cultural system with Chlorella vulgaris. The results show that self-regulation and inhibitive effect of bacteria-Z-QS01 to Chlorella vulgaris could implement through excreting chemic substance. Density of bacteria-Z-QS01 and concentration of chemic substance excreted by bacteria-Z-QS01 are the necessary conditions, which decide whether the regulation mechanism could be carried out or not. The enhanced UV-B radiation could affect quorum sensing of bacteria-Z-QS01 significantly, and the inhibitive effect to Chlorella vulgaris is decreased gradually with the dose increase of UV-B radiation. |
