Abstract

In order to assess the impact of cyanobacteria on mollusks under experimental conditions, the interaction of toxic and nontoxic strains of the cyanobacterium Microcystis aeruginosa (Kützing) Kützing and bivalve mollusks Unio pictorum (Linnaeus, 1758) has been studied. Cyanobacteria have a negative effect on bivalve mollusks: the 40% death of mollusks and deterioration of their adaptive capacity are recorded when cocultivated with M. aeruginosa at a high cell concentration. At the same time, there is no difference in the mortality of mollusks incubated with toxic and nontoxic cyanobacteria. A decrease in the content of microcystin-LR in the presence of bivalves is revealed. No statistically significant increase in the number of cyanobacteria in the water is noted after transit passage through the digestive system of bivalves.

Unio pictorum 对铜绿微囊藻有毒和无毒菌株存在的反应

摘要

为了评估实验条件下蓝藻对软体动物的影响，蓝藻有毒菌株和无毒菌株之间的相互作用铜绿微囊藻（ Kützing) Kützing 和双壳软体动物 Unio pictorum（Linnaeus，1758）已被研究。蓝藻对双壳类软体动物有负面影响：与M共培养时，软体动物死亡40%，适应能力下降。高细胞浓度下的铜绿假单胞菌。同时，用有毒和无毒蓝藻孵化的软体动物的死亡率没有差异。结果表明，在双壳类动物存在的情况下，微囊藻毒素-LR 的含量会降低。在通过双壳类动物的消化系统后，水中的蓝藻数量没有出现统计上显着的增加。
