Abstract
- Algicidal effect of red pigment of a marine bacterium Hahella chejuensis strain 96CJ10356 were tested with Cochlodinium polykrikoides, Gyrodinium impudicum, Heterosigma akashio, Procentrium micans and Alexandium catenella. Among the tested species three species of red-tide microalgae, Cochlodinium polykrikoides, Gyrodinium impudicum and Heterosigma akashio showed strong cell lysis in the presence of red pigment, which had maximum absorptions at 486 and 539 nm. In f/2 medium containing 1 mg/l ethanol-soluble crude red pigment, more than 99.1% of C. polykrikoides cells were lysed within 1 h, At the same conditions, cell lysis density of G. impudicum was 59.7, and H. akashiond 72.9%, respectively. After exposure to this pigment, the algal cells lose their motility, became round, expanded and finally burst.
