Alkaliphile

From Wikipedia, the free encyclopedia

Alkaliphiles are microbes classified as extremophiles that thrive in alkaline environments with a pH of 9 to 11 such as soda lakes and carbonate-rich soils. To survive, alkaliphiles maintain a relatively low alkaline level of about 8 pH inside their cells by constantly pumping hydrogen ions (H+) in the form of hydronium ions (H3O+) across their cell membranes into their cytoplasm.

Examples include:

  • Geoalkalibacter ferrihydriticus[1]
  • Bacillus okhensis [2]
  • Alkalibacterium iburiense[3]
