Ecophysiology of algae living in highly acidic environments

  author={Wolfgang Gross},
Highly acidic environments are inhabited by acidophilic as well as acidotolerant algae. Acidophilic algae are adapted to pH values as low as 0.05 and unable to grow at neutral pH. A prerequisite for thriving at low pH is the reduction of proton influx and an increase in proton pump efficiency. In addition, algae have to cope with a limited supply of carbon dioxide for photosynthesis because of the absence of a bicarbonate pool. Therefore, some algae grow mainly in near terrestrial situations to… CONTINUE READING
