Table 1.
Salinities and respective conductivities in different ecosystems and microbial domains
| NaCl | Conductivity (mS cm−1) | Water and microbes | Ecosystem | |
|---|---|---|---|---|
| g L−1 | % | |||
| 0.01 | 0.001 | 0.01 | Fresh water (non-halophilic microbes) | Rivers, soil, lakes |
| 0.5 | 0.05 | 0.47 | ||
| 1 | 0.1 | 0.94 | Brackish water (moderately and non-halophilic microbes) | |
| 30 | 3 | 28 | Saline water (moderately microbes) | Seas, oceans, some lakes |
| 40 | 4 | 38 | ||
| 50 | 5 | 47 | ||
| 100 | 10 | 94 | Brine water (strictly and moderately halophilic microbes) | Salt lakes and seas; brine lenses; cryopegs |
| 350 | 35 | 329 | ||
Salinities do not consider temperature and hydrostatic pressure and are solely based on the effect of NaCl concentration
