研究了病毒裂解对普氏棕囊藻（Phaeocystis pouchetii）感染株特异性病毒分离株的二甲基硫醚（DMS）、颗粒和溶解的二甲基磺基丙酸酯（DMSP）浓度的影响。20小时后，DMS浓度比对照培养物中观察到的水平增加了4倍，并且在加入病毒颗粒后45小时增加到8倍。结果表明，病毒裂解含DMSP的浮游植物细胞应被认为是一起自溶，放牧，细菌活动的过程中，可以影响海水中的DMS浓度。需要进一步研究以确定病毒在自然环境中的地球化学DMS循环中的重要性。
The effects of viral lysis on dimethyl sulfide (DMS) and particulate and dissolved dimethylsulfoniopropionate (DMSP) concentrations were studied in batch cultures of Phaeocystis pouchetii infected with a strain-specific viral isolate. After 20 h, DMS concentration had increased by fourfold over the levels observed in the control cultures, and this increased to eightfold 45 h after addition of viral particles. The results suggest that viral lysis of DMSP-containing phytoplankton cells should be considered alongside autolysis, grazing, and bacterial activity as a process that can influence DMS concentrations in seawater. Further research will be necessary to determine the importance of viruses in the biogeochemical DMS cycle in the natural environment.
