Harvesting of Spirulina platensis by cellular flotation
Jan 26 2005 · Aim To investigate an effective harvesting method for Spirulina platensis. Methods and Results Eighty per cent of S. platensis cells in the logarithmic growth phase were harvested by flotation when the cells were set in a static condition for 2 h. The optimum harvesting time was about day 6 of cultivation. The flotation activity of S. platensis cells was enhanced by the addition of NaCl.
