Paralytic shellfish poisoning (PSP) toxin profiles were compared among four culture strains of Alexandrium minutum. GTX-1, 2, 3 and 4 are the PSP toxins that occur in A. minutum, and other PSP toxins were not detected. When comparing the toxin profile of four A. minutum strains, GTX1 and 4 were the major toxins in Amtk1, Amtk2, and Amtk4, but in Amtk7, GTX3 and 2 were the major toxins. The results indicate that strains with various toxin profiles exist in southern Taiwan, and suggest that the comparison of the toxin profiles between strains at different localities is difficult. Additionally, the toxin profiles of A. minutum strains cultured in the same environment were different, suggesting that it was owing to the intrinsic nature of toxic algae.
对微小亚历山大藻的四个养殖菌株的麻痹性贝类中毒（PSP）毒素谱进行了比较。GTX - 1、2、3和4是在微小亚历山大藻中出现的PSP毒素，未检测到其他PSP毒素。在比较四个微小亚历山大藻菌株的毒素谱时，GTX1和4是Amtk1、Amtk2和Amtk4中的主要毒素，但在Amtk7中，GTX3和2是主要毒素。结果表明，台湾南部存在具有不同毒素谱的菌株，这表明比较不同地点菌株之间的毒素谱很困难。此外，在相同环境中培养的微小亚历山大藻菌株的毒素谱不同，这表明这是由于有毒藻类的内在特性所致。
