  • Figures 1 to 3 illustrate the FPP arrangement.
  • a FPP as described above was filled with Zarouk medium, and was inoculated with Spirulina platensis, to about 0.5 g/liter.
  • the air was pumped into a tube placed near to the bottom of the reactor, to keep the alga in suspension, and the temperature was kept at 35°C.
  • the alga was allowed to grow for 5 days.
  • a microscopic check showed an essentially pure culture. The yield was 4 g/1.
  • Example 2 A FPP as described above was filled with F2 medium, and was inoculated with Nanochloropsis salina to about 10 5 cells/ml. The air was pumped through a 0.2 ⁇ m filter into a tube placed near to the bottom of the reactor, to keep the alga in suspension, and the temperature was kept at 25°C. The alga was allowed to grow for 6 days. A microscopic check showed an essentially pure culture. The yield was 10 9 cells/ml. While the invention has been described using some specific examples, many modifications and variations are possible. It is therefore understood that the invention is not intended to be limited in any way, other than by the scope of the appended claims.
