The high subzero preservation of Spirulina: S. platensis CMU2 and S. platensis GD1 was performed by step wise freezing at 25, 4, and -20°C for 30 min. Then they were preserved at -80°C for seven months with four cryoprotectants: dimethyl sulfoxide, horse serum, calf serum and glycerol. The viability...
