Lower pH limit for the existence of blue-green algae: evolutionary and ecological implications
Brock TD. 1973. Lower pH limit for the existence of blue-green algae: evolutionary and ecological implications. Science. 179(4072):480-483
Observations on a wide variety of acidic environments, both natural and man-made, reveal that blue-green algae (Cyanophyta) are completely absent from habitats in which pH is less than 4 or 5, whereas eucaryotic algae flourish. By using enrichments cultures with inocula from habitats and various pH values, the absence of blue-green algae at low pH was confirmed.
