Cryoprotectans are used to preserve the cellular damages due to freeze-thaw cycles.
Biotechnological production of new cryoprotectans is demanding.
Colwellia psychrerythraea 34H produces a cryoprotectant exopolysaccharide.
The exopolisaccharide (EPS) primary and secondary structure has been finely characterised.
The molecular dynamics simulations (MD) suggest how the pseudohelicoidal structure inhibits the first hydration shell.
