为了了解卤虫(Artemia salina)对产麻痹性贝类毒素的塔玛亚历山大藻(Alexandrium tamarense)生长与产毒的影响,本文采用卤虫与有毒藻共培养的方法,研究卤虫对不同起始数量的亚历山大藻生长和产毒的影响。结果表明,当培养液中存在卤虫时,塔玛亚历山大藻的生长受到抑制,对数期缩短,最大藻细胞数量降低且与卤虫数量呈线性负相关,衰亡期细胞数量快速减少。在对数生长初期、中期,卤虫的存在对该藻单位细胞毒素含量影响不明显,但对数末期,可显著增加藻细胞毒素含量。
In order to understand the effects of artemia salina on the growth and toxigenicity of Alexandrium tamarense, a paralytic shellfish poison, this paper studied the effects of artemia salina on different initiation Effect of quantity of Alexandrium growth and toxigenicity. The results showed that the growth of Alexandrium tamarense was inhibited when Artemia salina was present in culture medium, the logarithmic phase was shortened, the maximum algae cell number was decreased and linearly negatively correlated with the number of Artemia, and the number of cells in the decay stage was rapidly decreased. In the early and middle logarithmic growth, the presence of Artemia did not significantly affect the cytotoxicity of the algae. However, at the end of the logarithmic phase, the cytotoxic content of algae was significantly increased.
