| The growth and microcystins production characteristics of three species of Microcystis (M. aeruginosa, M. ichthyoblabe, M. viridis) isolated from Yeongchun dam and Ankei dam in Kyungpook Province, South Korea were investigated at temperatures of $15{sim}35^{circ}C$ and light intensities of $35{sim}180;{mu}mol;m^{-2};s^{-1}$. All of the three species exhibited the highest growth rates (${mu}_{max}$) over the $30^{circ}C$. The maximum growth rates of M. aeruginosa and M. ichthyoblabe was observed at $70;{mu}mol;m^{-2};s^{-1}$, while M. viridis showed maximum growth rate at $35;{mu}mol;m^{-2};s^{-1}$. The maximum production of total microcystins was observed at $20^{circ}C$, and the production of microcystins decreased according as temperature increase. The highest microcystins production of M. aeruginosa, M. ichthyoblabe and M. viridis observed at light intensities of $120;{mu}mol;m^{-2};s^{-1}$, $70;{mu}mol;m^{-2};s^{-1}$ and $35;{mu}mol;m^{-2};s^{-1}$, respectively. The concentration of microcyst in production and microcystin types of three species according to temperatures and light intensities showed clear difference between the species. |
