Sažetak
Viruses are the most abundant and ubiquitous component of marine microbial plankton. To understand their dynamics, 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 at two stations in trophically different areas. Additionally, we gave the insight of the nutrient enrichment in the studied area with dissolved organic matter by viral lysis. Viral production was higher at the coastal station (0.75 ± 0.44 × 106 vlp mL-1 h-1) than at the open-sea station (0.49 ± 0.26 × 106 vlp mL-1 h- 1). Viral decay rates were also higher at the coastal sea station (0.25 ± 0.08 × 106 vlp mL-1 h-1) than in the open-sea station (0.14 ± 0.03 × 106 vlp mL-1 h-1), and were partially responsible for the reduction in produced viruses at both investigated stations (43.15 ± 25.19% at the coastal and 36.34 ± 21.91% at the open-sea station). The percentage of lysogenic bacteria was lower than that of lytic bacteria, which indicates the prevalence of the lytic cycle at both stations. Viruses had a significant influence on the mortality of bacterial cells in the coastal (78.81 ± 31.54%), and open-sea station (63.75 ± 8.80%), and thus contributed to the restoration of dissolved organic carbon, nitrogen and phosphorus into the microbial loop. All the abovementioned suggest that viruses are important part of the microbial food web and are an extremely important factor in the control of bacterial populations within the study area.
