Seasonal and Spatial Variability of Virioplanktonic Abundance in Haihe River, China
Figure 2
Comparison of total virus counts obtained by different treatments (1: reference; 2: filters with pore sizes of 0.1 μm; 3: no filtration; 4: fixation with 0.5% glutaraldehyde; 5: staining at room temperature; 6: without EDTA; 7: diluted in TE). The total virus count of each treatment was normalized to samples tested under reference conditions. Error bars represent the standard deviation ().
