选择我国沿海易发有毒赤潮藻——塔马亚历山大藻 [Alexandrium tamarense (Lebour) Balech,1 985 ]和从厦门海域筛选的海洋细菌作为实验材料 ,研究在实验生态条件下 A.tamarense的生理生态特征 ,及其与 3株从厦门海域筛选的海洋细菌 S5,S7,S10 与 A.tamarense共同培养表现的生态关系的差异性。结果表明 :在实验室条件下 ,A.tamarense可以较好地生长并保持自然状态下的若干特性 ,其生长曲线与微型生物的生长曲线相似 ;分别在藻细胞生长的延滞期和指数期加入细菌过滤液 ,发现 3种海洋细菌的过滤液对 A.tamarense生长有不同的抑制作用效果。三者的抑藻能力大小依次为 S10 >S5>S7。本文对海洋细菌抑藻作用机理、赤潮的生物防治可能性进行了讨论。
In order to study the physiological and ecological characteristics of A. tamarense (Lebour) Balech, 1890 and the marine bacteria screened from the Xiamen sea area as experimental materials, the ecotoxicological characteristics of A. tamarense (Lebour) , And their differences in ecological relationship with co-culture of three marine bacteria S5, S7, S10 and A. tamarense screened from Xiamen waters. The results showed that under laboratory conditions, A. tamarense grew well and maintained some characteristics under natural conditions. Its growth curve was similar to the growth curve of micro-organisms. Bacteria were added to the lag phase and exponential phase of algal cell growth respectively The filtrate, found that three kinds of marine bacteria filtrate on A. tamarense growth has a different inhibitory effect. The ability of algae-killing of the three was S10> S5> S7. In this paper, the mechanism of algicidal action of marine bacteria and the biological control of red tide were discussed.
