Russian scientists have found a way to paint extremophiles without killing them
Many archaea and some bacteria are able to live in unusual conditions: at extremely high temperatures, increased pressure, a significant concentration of salts in the water. Such microorganisms are called extremophiles.
However, it is not easy to find and study such bacteria and archaea. Most dyes used for cells of «ordinary» microorganisms do not work at increased salinity or high temperature.
The researchers found that the dye Mito Tracker, which is used for colouring the mitochondria, is suitable for extremophiles. It stains bacteria and archaea, while leaving them alive.
