Abstract

For the first time, experiments were performed using an ad hoc laboratory setup to study the mechanisms of the effects of low-intensity ultrasound on toxigenic cyanobacteria Synechocysctis sp. that prevail in the northwestern part of Russia. It is found that ultrasound triggers two stress-protective metabolic mechanisms of toxigenic cyanobacteria: (1) synthesis of polysaccharides and proteins to increase the thickness of cell walls and mucous membranes; (2) synthesis of toxins to suppress the external influence. Both mechanisms are extremely energy-consuming, depleting the vital resources of cyanobacteria and accelerating the process of cell death.

低强度超声对产毒蓝藻的影响

摘要

首次使用特设实验室设置进行实验，以研究低强度超声对产毒蓝藻集胞藻的影响机制。在俄罗斯西北部盛行。研究发现，超声波触发产毒蓝藻的两种应激保护代谢机制：（1）合成多糖和蛋白质，增加细胞壁和粘膜的厚度；(2)抑制外界影响毒素的合成。这两种机制都非常消耗能量，消耗蓝藻的重要资源并加速细胞死亡过程。
