基于羥基自由基高級(jí)氧化快速殺滅錐狀斯氏藻孢囊的研究
[Abstract]:Along with the ship ballast water transportation, our country faces the serious alien invasion biological risk, some of the spore sac formed by the red tide algae can become the "provenance" of the red tide, which seriously endangers the coastal marine environment. Therefore, it is very important to kill the cysts of red tide algae quickly and effectively. In this paper, hydroxyl radical (OH), produced by atmospheric pressure ionization discharge was used to kill the cysts of typical red tide algae. The threshold value and time for OH to kill cysts of Staphylococcus pyramidis were determined by SYTOX Green fluorescence staining method. The morphological changes of cysts were observed by scanning electron microscope (SEM). The results showed that the CT threshold of OH to kill cysts was 0.49mg min / L, and the time was 10 s. OH oxidized the chlorophyll, destroyed the DNA and inhibited the germination of cysts, which was superior to other methods. Therefore, a new method of killing algal cysts rapidly by OH plays an important role in the prevention and control of marine red tide disaster caused by alien invading organisms.
