Yeast exoglycoproteins produced under NaCl-stress conditions as efficient cryoprotective agents

Biological Procedures Online1:10


Six extracellular yeast glycoproteins were prepared from three yeast species in osmotic equilibrium and unequilibrium environments and used as non-penetrating cryoadditives. Glycoproteins secreted by the strain Dipodascus australiensis into growth medium containing NaCl (8% w/v) were found to be the most effective cryoadditives. It was possible to use these glycoproteins alone (without DMSO as penetrating agent) for the cryoprotection of the studied yeasts.
