Biology

Little is known about Phormidium pseudpriestleyi, but Antarctic cyanobacteria are generally characterised by their ability to cope with the harsh conditions of Antarctica, which include:

  • low temperatures
  • ice formation
  • high salt concentrations
  • several months of darkness during the Antarctic winter
  • high ultraviolet radiation during the summer
  • large variations in nutrient supply

Many Antarctic cyanobacteria produce antifreeze compounds and UV screens and are able to grow with very limited nutrients.
