| 中文摘要 | We studied the phagotrophic ability of dinoflagellate strain Karenia mikimotoi KM-Lu (isolated from the South China Sea), using fluorescent microspheres, bacteria isolated from the culture of K. mikimotoi and a marine microalgae Isochrysis galbana. We found that K. mikimotoi cultured under conditions of high light intensity could ingest fluorescent microspheres (diameters 0.5 and 2.0 mu m) and fluorescence-labeled bacteria and microalgae. Under a low light intensity, however, only fluorescent microspheres (diameter 0.5 mu m) and fluorescence-labeled microalgae were ingested. K. mikimotoi showed better growth by ingesting living marine bacteria or microalgae I. galbana than the controls, either in nutrient-depleted or nutrient-replete conditions. In nutrient-depleted conditions, the growth of K. mikimotoi was more significant with I. galbana as the prey item. In conclusion, the harmful dinoflagellate K. mikimotoi from the South China Sea has apparent phagotrophic ability, and some marine bacteria and microalgae may promote the growth of K. mikimotoi. |
