Abstract
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 the p H is less than 4 or 5, whereas eukaryotic algae flourish. By using enrichment cultures with inocula from habitats of various p H values, the absence of blue-green algae at low p H was confirmedKeywords
