Effects of water temperature, salinity and irradiance on the growth of toxic dinoflagellate Alexandrium catenella (AlCt-01) were investigated, which was isolated from Jinhae Bay, Korea. The maximum growth of A. catenella strain was obtained at $150{mu}E;m^{-2}s^{-1}$. The ranges of temperature and salinity for the growth of the strain were $15sim25^{circ}C$ and $20sim34$ PSU. The maximum growth rate of A. catenella determined was $0.45d^{-1}$ at $20^{circ}C$, 30 PSU and $150{mu}E;m^{-2}s^{-1}$ We also examined the Se and Fe effects on the toxic dinoflagellate A. catenella in optimal growth conditions. As Fe concentration of medium increased from 0 to $11.7{mu}M$, growth rate of A. catenella increased and the maximum growth rate(k=0.48 $d^{-1}$) was obtained at $11.7{mu}M$ of Fe cone. Growth of A. catenella were stimulated at> 1nM of Se. |
