To understand the activity of marine viruses, experiments on viral production, viral decay and the percentage of lytic and lysogenic bacterial cells among the total number of bacterial cells were carried out seasonally at two stations in the Adriatic Sea with different trophic conditions. Additionally, we are providing an insight on the enrichment with dissolved and particulate organic matter by viral lysis in the studied area. Viral production was higher at the coastal station than at the open-sea station. Viral decay rates were also higher at the coastal sea station than at the open-sea station, and accounted for approximately 40% of viral production at both investigated stations. The percentage of lysogenic infection was lower than that of lytical infection, which indicates the prevalence of the lytic cycle at both stations. Viruses had a significant influence on bacterial mortality through high daily removal of the bacterial standing stock at the coastal and open-sea station. The viruses contributed to the restoration of dissolved organic carbon, nitrogen and phosphorus in the microbial loop by lysing the bacterial cells at the studied stations. All the above suggest that viruses are important in the microbial food web and an important factor in the control of bacterial populations within the study area.

亚得里亚海中部两个营养不同区域的病毒动力学

为了了解海洋病毒的活性，在亚德里亚海的两个营养条件不同的季节，季节性进行了病毒产量，病毒衰减以及细菌细胞中溶菌和溶源细菌百分比的实验。此外，我们还提供了有关在研究区域通过病毒裂解富集溶解的和颗粒状有机物的见解。沿海站的病毒产量高于公海站。沿海海站的病毒衰减率也高于公海站，并且在两个调查站中约占病毒产量的40％。溶源性感染的百分比低于溶源性感染的百分比，这表明两个站的溶菌周期普遍存在。病毒通过每天大量清除沿海和远洋站的细菌站立种群，对细菌死亡率产生重大影响。这些病毒通过裂解研究部位的细菌细胞，有助于恢复微生物环中溶解的有机碳，氮和磷。所有以上表明，病毒在微生物食物网中很重要，并且是控制研究区域内细菌种群的重要因素。
