| Research Abstract |
Observations were carried out by using boreholes drilled in sedimentary geological setting in Horonobe, Hokkaido. Groundwater obtained from 140 m deep contained 4.5 ×103±1.7 ×103mL-1virus-like particles. Incubation experiment conducted pseudo in situ condition performed shortly after sampling showed that viral control of prokaryotic abundance was observed in 80 hours of incubation. A picture of virus-like particle was successfully taken by using Transparent Electron Microscopy, which showed the candidate of the virus-like particle was Caudovirales-like.
