Effect of Mg(OH)2 on motility of red tide organisms and its working mechanism

The motility inhibition and mechanisms of action of Mg(OH)2 on Heterosigma akashiwo, Chattonella marina and Heterocapsa circularisquama were evaluated. To determine the mechanisms of action of the biocontrol agent, an analog (polymer latex particles) which does not affect the pH of the medium was us...

Summary:The motility inhibition and mechanisms of action of Mg(OH)2 on Heterosigma akashiwo, Chattonella marina and Heterocapsa circularisquama were evaluated. To determine the mechanisms of action of the biocontrol agent, an analog (polymer latex particles) which does not affect the pH of the medium was used. Results demonstrated that the use of polymer latex particles alone does not inhibit the motility of the red tide organisms. On the other hand, the experimental section that raised pH had an inhibitory capacity. It confirms that motility suppression results from the combined effect of the physical contact of the particles with the red tide cells and the increase in pH of the medium following Mg(OH)2 application.
