The Change in Activity of Cyanophage PP by UV and Sunlight Radiation
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.
Utafiti wa Cyanophage PP na UV na Mionzi ya Jua: Utafiti wa UV na Mionzi ya Jua juu ya Utendaji wa Cyanophage PP ya Maji ya Mapema UV-A na UV-B zote mbili zilisababisha kutofanya kazi kwa kiasi kikubwa kwa cyanophage, ingawa athari ilikuwa tofauti. Kwa mfano, katika hali ya hewa ya hewa, kiwango cha inactivity ya cyanophage kwa jua katika majira ya joto na majira ya baridi kali ni 88.60% na 58.86%. Pia iligunduliwa kwamba licha ya mwangaza wa jua kuwa sawa katika vipindi fulani vya wakati katika misimu miwili, kiwango cha kutofanya kazi kilikuwa na utofauti mkubwa. Huenda sehemu tofauti-tofauti za mwangaza wa jua zikawa ndizo zinazosababisha tofauti hizo. Matokeo yalikuwa muhimu kwa kueleza mabadiliko ya msimu katika idadi ya cyanophage katika maji baridi.
