Low salinity and high-level UV-B radiation reduce single-cell activity in Antarctic sea ice bacteria
Experiments simulating the sea ice cycle were conducted by exposing microbes from Antarctic fast ice tosaline and irradiance regimens associated with the freeze-thaw process. In contrast to hypersaline conditions(ice formation), the simulated release of bacteria into hyposaline seawater combined wit...

Summary: | Experiments simulating the sea ice cycle were conducted by exposing microbes from Antarctic fast ice tosaline and irradiance regimens associated with the freeze-thaw process. In contrast to hypersaline conditions(ice formation), the simulated release of bacteria into hyposaline seawater combined with rapid exposure toincreased UV-B radiation significantly reduced metabolic activity. |
