This study evaluated the possibility of using to prevent and control harmful algae blooms. Firstly, and were co-cultured to assess the competition for nutrients between them. Different physiological and biochemical parameters, such as growth, cell membrane permeability and esterase activities were determined in exudate culture experiment to investigate allelopathic effects of culture and mixed cultures ( and ) at different growth phase on harmful microalgae (). Results showed that could significantly inhibited when volume ratios were 4:1 and 1:1 () in co-culture experiment. Further, it was found that the membrane system of was disintegrated by the culture filtrate of at exponential phase. In addition, esterase activities and photorespiration were significantly inhibited. In conclusion, exhibited different allelopathic effects at different growth phase. Its exponential phase showed a significant inhibitory effect, while no inhibitory effect was observed at the decline phase.
本研究评估了利用 来预防和控制有害藻类水华的可能性。首先，将 和 共培养，以评估它们之间对营养物质的竞争。在渗出物培养实验中，测定不同的生理生化参数，如生长、细胞膜通透性和酯酶活性，以研究不同生长阶段 的培养物和混合培养物（和）对有害微藻（）的化感作用。结果表明，在共培养实验中，当体积比为 4:1 和 1:1（）时， 可以显著抑制 。此外，研究发现 对数期的培养液可以使 的膜系统解体。此外，酯酶活性和光呼吸受到显著抑制。总之， 在不同的生长阶段表现出不同的化感效应。其对数期表现出显著的抑制作用，而衰退期则没有观察到抑制作用。
