Abstract:

The optimal media was selected by a media choosing experiment on growth of toxic marine dinoflagellate Coolia monotis isolated from tropic coral reef waters around Sanya, Hainan Island. Based on the result, the influence of different concentrations of three trace elements, Fe, Mn, and Co, on growth and toxin-producing of C. monotis were studied by an or-thogonal experiment. Our results show that the optimal media is K series among Erd, f/2, GP, and K media. The maximum average growth rate exhibits under the concentrations of 2?10?5mol•L?1, 1?10?6mol•L?1, and 5?10?7mol•L?1 for Fe, Co, and Mn, respectively. When concentrations were 5?10?6mol•L?1 for Fe, 1?10?7mol•L?1 for Co, and 2?10?6mol•L?1 for Mn, C. monotis presented the strongest toxicity.
