  • The results of UV and sunlight on the activity of freshwater cyanophage PP are presented in this paper. Both UV-A and UV-B resulted in significant inactivity of cyanophage, though the effect was different. The outdoor performance showed that the day inactivity rates of cyanophage by sunlight in summer and winter were 88.60% and 58.86%, respectively. It was also found that in spite of the similar sunlight intensity at some time interval in two seasons,the inactivity rate was of a considerable diversity. Different sunlight constituent might be responsible for the diversity. The results were useful for explaining the seasonal change in cyanophage population in freshwater.

    Abstract: The results of UV and sunlight on the activity of freshwater cyanophage PP are presented in this paper. Both UV-A and UV-B resulted in significant inactivity of cyanophage, though the effect was different. The outdoor performance showed that the day inactivity rates of cyanophage by sunlight in summer and winter were 88.60% and 58.86%, respectively. It was also found that in spite of the similar sunlight intensity at some time interval in two seasons,the inactivity rate was of a considerable diversity. Different sunlight constituent might be responsible for the diversity. The results were useful for explaining the seasonal change in cyanophage population in freshwater.
