On the residual water content of dried but viable cells


We have examined the residual water in dried cysts of the brine shrimp,Artemia salina, by gas-bombardment techniques at reduced pressures and temperatures. This treatment reduced, but did not remove all the residual water, the lower limit being about 0.0069 gH2O/g dried weight. The significance of such small amounts of water to cell hydration is assessed. The treatment did not appreciably reduce the viability of this cyst population.
