Storage of Pavlova viridis by Encapsulation-dehydration under Normal Temperature and Low Temperature

Abstract: Pavlova viridis was preserved by encapsulation-dehydration under normal temperature and low temperature. The main factors influencing the algal viability， such as different temperature， illumination intensities and the water content of beads， were studied. The results showed that alginate beads were stored for 6 months under normal temperature and low temperature and the high viability were obtained through adjusting the water content， controlling illumination intensities and using glycerin. The algae viability reached about 77.6% at 4 ℃ (dark). After preservation， the growth rates of algae could reach the normal level in the conditions suitable for recovery. Encapsulation-dehydration is simple without the requirement for specialist equipment， so it has a bright application prospect in the algae preservation.
