研究了温度对赤潮异弯藻病毒HaV溶藻活性和稳定性的影响。akashiwo（针藻纲），通过生长H.在各种条件下接种HaV的akashiwo培养物。温度和宿主培养物的生长阶段被认为是决定HaV杀藻活性的重要因素。HaV溶藻活性的最适温度范围为20 ~ 25°C。比较在不同温度下的哈akashiwo株的病毒易感性和HaV克隆的杀藻活性，两者都被认为是表型多样的。还评估了温度对HaV稳定性的影响。HaV显示出感染性滴度的相对快速降低，即使在黑暗中保存在5°C下。文中还讨论了HaV在自然环境中的行为和H.赤潮红潮。
The effect of temperature on the algicidal activity and stability of HaV (Heterosigma akashiwo virus), which infects the harmful bloom causing alga, H. akashiwo (Raphidophyceae), was determined by growing H. akashiwo culture inoculated with HaV under various conditions. Temperature and growth stage of the host culture are considered to be important factors determining the algicidal activity of HaV. The optimum temperature for the algicidal activity of HaV ranged from 20 to 25°C. Comparing the viral susceptibility of H akashiwo strains and the algicidal activity of the HaV clones at different temperatures, both were suggested to be phenotypically diverse. Effect of temperature on the stability of HaV was also evaluated HaV showed a relatively rapid decrease in infectious titer even when preserved at 5°C in the dark. The data is discussed in relation to the behavior of HaV in natural environments and the disintegration mechanism of H. akashiwo red tide.
