Abstract
The algicidal effects of red pigment from the marine bacterium Hahella chejuensis strain 96CJ10356 on two species of red-tide microalgae (Cochlodinium polykrikoides and Gyrodinium impudicum) were examined. The isopropanol-soluble crude red pigments with maximum absorptions at 496, and 533.5 nm, were produced. Swimming cell density of C. polykrikoides and G. impudicum decreased to less than 8% of the initial density within 1 h in f/2 medium containing 10 mg/l crude red pigment. After losing their motility, almost all of the cells became round and then expanded and burst. Once cells had become round, none of them recovered to normal vegetative cells within 24 h even if they were transplanted to f/2 medium.
