Mechanism of CO₂ acquisition in an acid-tolerant Chlamydomonas

The acid-tolerant green alga Chlamydomonas (UTCC 121) grows in media ranging in pH from 2.5 to 7.0. Determination of the overall internal pH of the cells, using ¹⁴C-benzoic acid (BA) or [2-¹⁴C]-5,5-dimethyloxazolidine-2,4-dione (DMO), showed that the cells maintain a neutral pH (6.6 to 7.2) over an...
