| Abstract: | Six extracellular yeast glycoproteins were prepared from three yeast species in osmoticequilibrium and unequilibrium environments and used as non-penetrating cryoadditives. Theglycoprotein secreted by the strain Dipodascus australiensis into the growth mediumcontaining NaCl (8% w/v) was found to be the most effective cryoadditive. It was possible to usethis glycoprotein alone (without penetrating agent DMSO) for the cryoprotection of the yeastsstudied. |
