摘要(Abstract)：

海洋卡盾藻(Chattonella marina)是我国南方重要的有害赤潮原因种,其产生的溶血毒素、活性氧等可能是造成鱼类死亡的重要原因.在实验室条件下,研究了氮、磷和铁等营养盐对海洋卡盾藻生长及产毒的影响,以期为阐明海洋卡盾藻溶血毒素生成机制奠定基础.研究结果发现:在铁、氮、磷盐三因素四水平正交实验条件下,铁盐和氮盐是影响海洋卡盾藻生长的显著因子;氮盐和磷盐是影响海洋卡盾藻产毒的显著因子;铁盐浓度0.492mg·L-1、氮盐浓度375mg·L-1、磷盐浓度5mg·L-1时海洋卡盾藻的比生长速率最大;铁盐浓度0mg·L-1、氮盐浓度375mg·L-1、磷盐浓度0.5mg·L-1时海洋卡盾藻的产毒能力最强,即高氮、低磷条件下有利于海洋卡盾藻溶血毒素的合成.
