本文报道了改性粘土对有害藻华（HAB）中trochoidea斯克里普氏菌囊形成的影响。在培养液中加入浓度分别为0、0.1、0.5和1.0 g/L的改性粘土，并在实验室控制条件下对棘球蚴的囊体进行观察。结果表明，当粘土浓度为1.0 g/L时，藻细胞的去除率可达97.7%。当粘土浓度从0 g/L增加到1.0 g/L时，囊肿形成率从4.6%增加到24.6%。两种囊肿变性：脊柱钙质囊肿和光滑的非钙质囊肿。当粘土浓度从0 g/L增加到1.0 g/L时，脊髓囊肿的比例从76.9%下降到24.1%。此外，改性粘土对包囊萌发有影响。发芽率随粘土浓度的增加而降低。非钙质包囊萌发率较低，萌发时间较长。由此可见，改性粘土能抑制藻细胞增殖，促进巨形拟南芥时间囊的形成，可能有助于控制赤潮藻华暴发。
We present results on the effect of modified clay on cyst formation of Scrippsiella trochoidea in harmful algal bloom (HAB). Modified clay (in concentration of 0, 0.1, 0.5, and 1.0 g/L) were added to cultures, and observations were made on cysts of S. trochoidea under controlled laboratory conditions. Results indicate that the removal rate of algal cells reached 97.7% at the clay concentration of 1.0 g/L. The cyst formation rate increased from 4.6% to 24.6% when the concentration of clay was increased from 0 to 1.0 g/L. Two cyst metamorphs were observed: spinal calcareous cysts and smooth noncalcareous ones. The proportion of the spinal cysts decreased from 76.9% to 24.1% when clay concentration increased from 0 to 1.0 g/L. In addition, modified clay affected cyst germination. The germination rate decreased with the increases in the clay concentrations. Non-calcareous cysts had a lower germination rate with a longer germination time. We conclude that modified clay could depress algal cell multiplication and promote formation of temporal cysts of S. trochoidea, which may help in controlling HAB outbreaks.
