Table 1 Viral turnover rate (VTR), viral turnover time (VTT), virus-mediated prokaryotic mortality rate (VMM), percentage of prokaryotic cells lysed by viruses per hour, virus-induced prokaryotic turnover time (VPTR), and rate of carbon release by lysis in the sediments of Hole M59C. VMM was calculated by dividing lytic viral production by a mean burst size of 45, a mean number obtained from a global survey of surface sediments

From: Active and diverse viruses persist in the deep sub-seafloor sediments over thousands of years

  1. Note: Source Ref. [8]. The percentage of cells lysed was determined by dividing VMM by prokaryotic cell abundance. Carbon released by viral lysis = VMM × cell carbon content, and prokaryotic carbon content were based on an estimate of 20 fg C cell−1 in the sub-seafloor sediments of Baltic Sea [8]. Note that the data represent potential rates obtained from incubation experiments and exceed the natural rates
