Table 3 The effect of different CO 2 concentrations supplied by flue gas (Fl) and one concentration supplied by pure liquid CO 2 gas (C) on pH and dry weight concentration (n=3, ±SE) after 4 and 5 days of C. reinhardtii grown at 300 μmol m -2 s -1 PFD

  1. The productivity from day four to five was calculated as the increase in culture concentration, in g dry weight production per m2 and day, as well as in g dry weight produced per mol of photosynthetic active radiation.
  2. For significance levels see Table 2 footnote.
